Suggested April 2024 What Is Metaverse And What Does It Have To Do With Facebook

Mark Zuckerberg loves to be dramatic and mysterious, which makes the sudden Facebook rebranding to Meta less surprising. However, it’s more confusing than anything for most people. What is metaverse and how exactly does it relate to Facebook? The two tie together more than you might believe, but first, let’s dive into what “metaverse” means and how you might already be a part of it.

What is Metaverse?

Neal Stephenson is typically credited with coming up with the term metaverse in his popular 1992 sci-fi novel “Snow Crash.” In his novel, he envisioned a futuristic world where people interacted in virtual worlds using avatars. If that future sounds more like now, then you’d be right.

The ultimate purpose of the metaverse is to serve as an alternative to reality by using a combination of virtual reality (VR), augmented reality (AR), video/voice communication, 3D avatars, and more.

For example, if you wanted to hang out with friends, you’d never leave the house. Instead, you’d use technology to step into a realistic virtual world where you and your friends would hang out in avatar form. You might go to a concert, watch a movie together, play games, or just sit around and talk. It’d be just like real life but more convenient in many ways, especially if you live far apart.

To answer the question of what is metaverse: it’s a digital universe where you live, play, interact, and even work. In fact, in the popular virtual community/game Second Life, many users work full-time jobs creating and selling digital goods.

You’re Already a Part of the Metaverse

While not everybody is technically a part of the metaverse, millions already are, and you probably never even realized it. For example, if you’re an iPhone user, how often have you communicated using your custom memoji? While it’s a simplistic example, you’re using an avatar version of yourself to communicate digitally.

If you love playing video games, you probably already have avatar versions of yourself that interact with other characters (real people, not NPCs). This is the metaverse in action. Minecraft, Fortnite, and Roblox are three highly popular examples where users are living and playing in the metaverse.

You could even consider some types of online meetings to be part of the metaverse. For instance, if a team uses a virtual meeting space where everyone’s avatars gather together to chat, this is the metaverse. The idea is to have a more immersive experience than just your standard video chat.

The great thing about it is it’s so simple to step into this virtual universe and interact as if you were simply walking down the street. In many cases, it doesn’t feel that much different.

It’s More than Just Virtual Reality

If you’re thinking that the metaverse is just virtual reality, you are only partially right. VR is an integral part of the metaverse. But, it’s not all it is. VR on its own just involves feeling like you’re a part of another reality or to experience something in a risk-free environment.

For example, healthcare professionals use VR to test new surgeries or during training to get experience before working with live patients. People dealing with mental health issues, such as anxiety or PTSD, use VR to step into calming worlds where they don’t have to feel afraid or worried.

With the metaverse, you add a social element. It’s not just about you – it’s an entire world or universe. Using the healthcare example, a full team might practice a surgery together or PTSD patients from around the world might meet together in a virtual room to talk, hang out, and deal with their trauma together.

This universe takes your daily life and brings it online. As the technology improves, you’ll see avatars transforming from cartoonish and obviously digital to holographic versions that look nearly real.

With all of the above to consider, why did Zuckerberg suddenly decide Facebook should be called Meta? The first reason is simple enough: to sound more cutting edge. The second reason is because Facebook is investing heavily in the metaverse future with over $10 billion this year alone. In fact, the company invested $150 million in immersive learning to prepare creators for developing the new meta reality.

The name is designed to encompass all of Facebook’s apps and technologies under one brand. The purpose is to become a truly metaverse company. In layman’s terms, you’d be able to live in a Facebook world. Instead of scrolling through posts, you’d actually hang out virtually with friends, go to work meetings (using Horizon Workrooms), watch movies together, attend events, and much more. Zuckerberg wants Facebook to be known as where you go to step into the metaverse.

Since Facebook, WhatsApp, and Instagram are all keeping their names, what does Meta even mean? The original Facebook brand also included devices and other platforms, such as Portal and Oculus Quest, with future devices in the works. Currently, the company’s at work creating a universal account system that’ll work with all Meta properties, so you won’t be required to have a Facebook account.

It’s all more conceptual right now than reality. Rebranding to Meta is just the start. While some feel it’s just a way to distract from all the negative news about Facebook in the last several years, it could be that Zuckerberg doesn’t want to miss out on an emerging and already popular market. It’s worth taking a look at the official announcement to see what Zuckerberg is envisioning.

Facebook’s Not Alone in Investing in the Metaverse

Facebook is far from the only or even the first to invest in the metaverse concept. As mentioned before, Minecraft, Roblox, and Fortnite have already invested in the future and players already get to experience the metaverse for themselves.

Epic Games, which is the company behind Fortnite, has helped users attend concerts virtually with artists such as Travis Scott and Ariana Grande. You could even step back in time to experience the iconic “I Have A Dream” speech from Martin Luther King Jr.

To make gaming even more realistic, Epic’s working on creating photorealistic avatars using MetaHuman Creator. The beta launched in April 2023. The tool helps platforms create “digital humans” in around an hour. Imagine being able to go to a concert with a few friends without ever leaving your home, yet all of you look exactly like yourselves and not the typical cartoonish animated avatar. This is what Epic’s investing in.

Obviously, Microsoft isn’t about to be left out of the metaverse. The tech giant is adding metaverse features to Microsoft Teams as early as 2023. This will include virtual avatars and holograms, which will allow teams to meet in real time at a virtual office or other virtual locations.

Microsoft’s also working on creating full 3D workplaces and retail environments. This would allow employees and customers to interact together in a more realistic environment but from the comfort of home, a local coffee shop, or anywhere with a good Internet connection.

Stepping into the Metaverse

More and more companies are jumping onboard the metaverse train. Everyone wants to be the first to offer the most immersive, fun, and useful experiences possible. But, what can you actually do in the metaverse?

Some of the top examples right now involve video games or game developers. But you can do far more than just play games with friends or random strangers around the world.

After remote work became the new norm for millions in 2023, you may already realize how lonely and strange the experience can be if you’re used to working with others all day long. In a metaverse world, remote work may mean you stay at home but still go to meetings, gather at the watercooler during breaks, get together to hangout with co-workers after work, and even work side by side on big projects. Naturally, this is all virtual, but you get the benefits of remote work and actually being at work at the same time.

While VR and AR have already been used to help with training in various fields, training becomes far more in depth and realistic thanks to fully virtual worlds. Soldiers can train together and practice scenarios safely, for instance.

The metaverse can transform nearly any experience, including how you exercise. Hate the gym? No problem. Step into a virtual studio to attend a fitness class without ever leaving home and get real-time feedback from instructors. Attend classes at any university and even gather in study groups without being on a campus.

The metaverse offers the chance to do nearly anything virtually. Attend concerts, explore museums, travel the world, celebrate holidays, experience major events in history, browse store shelves, and much more.

Cryptocurrency is another area affected by the metaverse. Grayscale, a crypto company, estimates the metaverse could be a $1 trillion industry in years to come. Part of the appeal could come in the form of cryptocurrency. For instance, try your luck in virtual casinos with other real players. Win and lose real crypto.

Art galleries, celebrities, and brands are all launching NFTs, letting users buy unique digital goods. Much like real items, value can increase over time, making these popular investments for people. Anyone can hold concerts, accepting cryptocurrency as payment.

Of course, virtual platforms often have their own currencies, which users can trade out for real money or use on other platforms that accept various crypto. There is a wide variety of metaverse games in the blockchain space that you can play right now.

Some metaverse platforms are also taking a lesson from cryptocurrency and creating decentralized platforms where users own everything versus a single company owning it, like Meta would own its metaverse.

For example, Decentraland is a virtual world owned by players. You can buy and sell virtual plots of land, a form of NFT, using MANA, which is cryptocurrency based on the Ethereum blockchain. In fact, one plot of land sold for $2.43 million. This shows just how valuable metaverse property is becoming.

Frequently Asked Questions 1. Do I need special equipment or software to be a part of the metaverse?

On the other hand, you can play Fortnite, create your own games in Roblox, create your own personal metaverse in Minecraft, or step into a virtual life in Second Life without any special equipment outside of a computer, mobile device, or gaming console.

Mainly, you’ll need a strong high-speed Internet connection.

2. What is mixed-reality?

While the metaverse relies heavily on VR and AR, mixed-reality is a more commonly used term for many metaverse experiences. This is where the virtual and real worlds meet. For instance, something as simple as an Instagram filter is considered mixed-reality.

A more extreme example is holographic 3D avatars. For instance, a friend may “appear” in your living room as a holographic version of themselves. Or a school may use holographic models to help students learn to work on machinery.

3. Can I live and work in the metaverse?

Technically, yes. In fact, that’s how some companies envision the future. You won’t need to leave home to go to work or meet with friends. In reality, you’ll always need to live in the real world at least some of the time.

However, it’s becoming more normal to have remote doctor appointments, virtual therapy sessions, and virtual meetings.

As shown in examples throughout this article, some people do make a full-time living just in metaverse worlds by creating digital goods or hosting virtual experiences, such as concerts and speaking engagements.

4. When will the metaverse become the norm?

That’s harder to answer. It’s already normal in many ways, such as gaming. But, it could still be years before it’s just as normal to go to a virtual concert as an in-person concert. As the technology behind the metaverse changes, experiences in the metaverse will feel more real, which will lead to higher adoption rates.

What Is Spooler Subsystem App? Why Does It Have High Cpu Usage

Spooler Subsystem apps are integral in operating a printer and giving it commands to print, scan or send a fax. This Windows service is like a middleman between your PC and the printer. 

Thankfully, this issue is quickly resolved mainly through performing a software update or a quick clearing of the printer queue. The only way to tell if the spooler subsystem app is malfunctioning is when you open the task manager and notice that it’s taking too much of your CPU resources. 

Is the Spooler Subsystem App a Virus?

The spooler subsystem app comes by default with any Windows operating system and is completely safe and made to serve a specific purpose. However, malware is out there that masks ordinary processes to circumvent your antivirus systems.

What Causes High CPU Usage for the Spooler Subsystem?

Here is a list of the most common reasons why you get very high CPU usage for this application:

Your Printing queue is full: This is perhaps the most common reason why you get high CPU usage for the Spooler subsystem app.

Queuing of files set for printing enters a loop: Any loop would cause very high CPU usage, as it goes on indefinitely until stopped.

Your printer has encountered an error: If the printer encounters an error, it might constantly try to resolve it with the operating system – causing abnormally high CPU usage

Outdated drivers: In rarer cases, the problem is caused due to an improperly configured PC or printer driver.

Your system has malware masking as a Spooler subsystem app: Some malware are specially designed to mimic windows processes in order to bypass the defenses.

How to Fix Spooler Subsystem App With a High CPU Usage?

As a non-essential Windows process, seeing that this application takes up more than 1% of your CPU is abnormal and is, in essence, wasted performance. This article will show you how to fix high spooler subsystem CPU usage as well as how to prevent this bug in the future. Here are the different ways to fix it:

Use the Built-in Troubleshooter

Let the process finish, restart your PC and check if the spooler subsystem’s high CPU issue persists. 

Clear the Printer Queue

Here are the steps to clear the printer queue:

Disable the Process

A quick solution to temporarily resolve this issue is by forcing windows to stop running the process manually. Here are the exact steps to do so:

You will notice that it is completely gone if you check your task manager. While this fix works wonders, the con is that you might have to perform it every time you encounter a high CPU usage problem.

Update Your Drivers

Having the latest drivers for both your Printer and PC can prevent a spooler subsystem from malfunctioning. In general, there are two ways to update a printer’s drivers. The first is by using the built-in Windows driver update function, and the second is by using the printer manufacturer’s driver assistant application. 

Since every printer manufacturer has a slightly different proprietary app that can install drivers, we will show you the universal way to do so via the Windows Driver Update function:

After the procedure is finished, restart your computer and check if the high CPU usage issue persists. 

Reset Your Printer 

This last resort measure involves performing a factory reset on your printer. When a printer’s internal memory and settings are reset, this might clear up an error in the printing queue system that causes abnormally high CPU usage. 

Every printer has a different way to perform a factory reset; some require you to go to the printer’s settings via its built-in interface, while others require a simple prolonged holding of the power button. In any case, check your printer’s instruction manual online to find the specific steps to perform a factory reset.

After the reset is done, restart your devices, then open up your Windows task manager and check if the issue persists. 

What Is A Digital Footprint And What Does It Tell About You?

What Is A Digital Footprint And What Does It Tell About You? What is Digital Footprint? How To Know More About Your Digital Footprints?

Though there is no patented way to know about all the information about you available on the Internet, you can try a few things. To begin with, you can start by searching specifics like “FirstName LastName@” to be aware if there is an email address with your name that you may not be aware of. Secondly, you can try and search for “FirstName LastName filetype: doc” to check there is a document on the web with your name on it. You can try and repeat it with other file extensions like image files and pdfs.

Apart from these manual methods, there are a few online tools to help you determine what is all the information available on the internet. HaveIBeenPwned is a website to help you determine if your email address has ever been compromised in any of the data breaches. Similarly, PeekYou, FamilyTreeNow, and Radaris also help to determine the digital footprints you have on the internet.

How do you Minimize your Digital Footprints over the Web? 1.  Encrypt your Data with a VPN:

Though there are a lot of VPNs available out there in the market, we suggest using Systweak VPN for Windows Operating System.

Systweak VPN:

This Systweak VPN is one of the most secure VPNs available in the market. Systweak VPN employs industry-best security measures to keep your data private over the web. For Example,

Systweak VPN can help mask your IP Address with a different one so the website you visit never gets to see your IP Address and hence, can’t determine your real location.

Because Systweak VPN allows you to use several different servers around the web, you don’t have to worry about cookies tracking you everywhere because they would never know that it is you who is surfing all those websites.

Also, because Systweak VPN uses AES 256-Bit Encryption, all the data that you send or receive over the web is secure.

With all the amazing features and more, Systweak VPN is one of the most secure VPNs available in the market.

2.  Be prudent about what you disclose online:

Another demonstrated technique for protecting your security is to be very cautious and careful about what you do on the web. Try not to share all your subtleties on the web, don’t fill forms on any or every website, don’t go around pursuing insecure sites. The less data you uncover, the better. Remember that everything you share on the internet can be caught and held, conceivably for a significant period.

3.  Social Media Privacy Settings:

Most of us don’t bother much about what we share on our social media and to whom we let it be shown. Make sure that you have your Social Media accounts’ information only visible to your friends and no one else other than that should know what you post, where you went, etc.

What Is Computational Photography And Why Does It Matter?

What is computational photography?

Robert Triggs / Android Authority

The term computational photography refers to software algorithms that enhance or process images taken from your smartphone’s camera.

You may have heard of computational photography by a different name. Some manufacturers like Xiaomi and HUAWEI call it “AI Camera”. Others, like Google and Apple, boast about their in-house HDR algorithms that kick into action as soon as you open the camera app. Regardless of what it’s called, though, you’re dealing with computational photography. In fact, most smartphones use the same underlying image processing techniques.

Techniques and examples of computational photography

With the basic explanation out of the way, here’s how computational photography influences your photos every time you hit the shutter button on your smartphone.

Portrait mode

Super resolution zoom / Space zoom

Night mode / Night Sight

Replace the whole sky

Here’s a fun application of computational photography. Using the AI Skyscaping tool in Xiaomi’s MIUI Gallery app, you can change the color of the sky after you capture a photo. From a starry night sky to a cloudy overcast day, the feature uses machine learning to automatically detect the sky and replace it with the mood of your choice. Of course, not every option will give you the most natural look (see the third photo above), but the fact that you can achieve such an edit with just a couple of taps is impressive in its own right.

Face and Photo Unblur

Action pan and long exposure

A brief history of computational photography

Even though you may have only recently heard about it, computational photography has been around for several decades. However, we’ll only focus on the smartphone aspect of the technology in this article.

In 2013, the Nexus 5 debuted with Google’s now-popular HDR+ feature. At the time, the company explained that the HDR+ mode captured a burst of intentionally over- and under-exposed images and combined them. The result was an image that retained detail in both, shadows and highlights, without the blurry results you’d often get from traditional HDR.

Machine learning enabled features like night mode, panoramas, and portrait mode.

Apple eventually followed through with its own machine learning and computational photography breakthroughs on the iPhone XS and 11 series. With Apple’s Photonic Engine and Deep Fusion, a modern iPhone shoots nine images at once and uses the SoC’s Neural Engine to determine how to best combine the shots for maximum detail and minimum noise.

We also saw computational photography bring new camera features to mainstream smartphones. The impressive low-light capabilities of the HUAWEI P20 Pro and Google Pixel 3, for instance, paved the way for night mode on other smartphones. Pixel binning, another technique, uses a high-resolution sensor to combine data from multiple pixels into one for better low-light capabilities. This means you will only get a 12MP effective photo from a 48MP sensor, but with much more detail.

Do all smartphones use computational photography?

Most smartphone makers, including Google, Apple, and Samsung, use computational photography. To understand how various implementations can vary, here’s a quick comparison.

On the left is a photo shot using a OnePlus 7 Pro using its default camera app. This image represents OnePlus’ color science and computational photography strengths. On the right is a photo of the same scene, but shot using an unofficial port of the Google Camera app on the same device. This second image broadly represents the software processing you’d get from a Pixel smartphone (if it had the same hardware as the OnePlus 7 Pro).

Right off the bat, we notice significant differences between the two images. In fact, it’s hard to believe we used the same smartphone for both photos.

Looking at the darker sections of the image, it’s evident that Google’s HDR+ algorithm prefers a more neutral look as compared to OnePlus, where the shadows are almost crushed. There’s more dynamic range overall in the GCam image and you can nearly peer into the shed. As for detail, both do a decent job but the OnePlus does veer a tad bit into over-sharpened territory. Finally, there’s a marked difference in contrast and saturation between the two images. This is common in the smartphone industry as some users prefer vivid, punchy images that look more appealing at a glance, even if it comes at the expense of accuracy.

Even with identical hardware, different computational photography methods will yield different results.

This comparison makes it easy to see how computational photography improves smartphone images. Today, this technology is no longer considered optional. Some would even argue that it’s downright essential to compete in a crowded market. From noise reduction to tone mapping depending on the scene, modern smartphones combine a range of software tricks to produce vivid and sharp images that rival much more expensive dedicated cameras. Of course, all this tech helps photos look great, but learning to improve your photography skills can go a long way too. To that end, check out our guide to smartphone photography tips that can instantly improve your experience.


No. Computational photography is a software-based technique used by smartphones to improve image quality. On the other hand, computer vision refers to using machine learning for detecting objects and faces through images. Self-driving cars, for example, use computer vision to see ahead.

Yes, iPhone embraced computational photography many years ago. With the iPhone XS and 11 series, Apple introduced the Smart HDR and Deep Fusion.

What Is Dropbox Paper And How Does It Compare?

Dropbox announced Dropbox Paper in 2024 and launched the product in 2023 as a new way to organize and collaborate with team members from anywhere in the world. Essentially, it wanted a piece of the online collaborative pie that has been held hostage predominantly by Google Drive and Office 365.

It’s been a long and winding road during a short period of time for Dropbox Paper. What is Dropbox Paper and has it held up to the competition or crashed and burned under the weight of its own hype?

Table of Contents

What Is Dropbox Paper?

Dropbox Paper is a collaborative editing service with drag and drop features. It’s incredibly flexible, allowing teams of all sizes to come together to create, review, revise, manage, and organize creative ideas. Think of it as a giant, virtual whiteboard that all members of a team can interact with simultaneously.

Paper has recently been integrated into Dropbox itself, no longer considering it to be a standalone service. This means you’ll need a Dropbox account to use Paper. However, anyone who is currently using Paper will retain all documents created, only now they will appear in Dropbox in a .paper format.

Dropbox Paper Versus Competitors

“When you come for the king, you had better not miss”. This phrase seems all too relevant when stacking up Dropbox Paper to Google Docs. In this comparison, Paper should have spent more time at the shooting range.

In all fairness, a direct comparison shouldn’t really be a discussion. Aside from collaboration efforts, they’re not even similar in most respects. Google Docs is a style and editing tool for word documents, whereas Paper represents something closer to collaborative note-taking software.

If anything, Dropbox Paper seems to imitate Evernote and Microsoft’s OneNote far more than anything you’d find on Google Drive.

Versus Evernote

Evernote is and was always meant to be a note-taking tool. You brainstorm an idea and Evernote provides a place for you to jot it down and save it for later. You can then categorize these notes with tags for organizational purposes.

Dropbox does things a little different. Saved documents are filed under folders. This is one of the similarities it has with the Google Docs and Microsoft. This system allows you to create as many folders within folders as you’d like. Quite a step up from Evernote’s limited depth.

Both options provide basic text formatting (bold, italics, bullet points, etc.) Where Evernote earns some points is the ability to support image editing through Skitch. Paper also requires a third-party editing service but does not directly support any which means you’re on your own with the search choices.

Both services have similar ways to share. Paper uses an Invite button whereas Evernote has a Share button. Both allow for permission control over who can edit and view.

When it comes to collaboration, Paper shines brightest. It allows you to draw the attention of a particular note through an @mention. You can then create to-do lists and assign individual tasks to the varying members of your team.

Both options are great but Evernote never had collaboration in mind during its creation. Though they share common ground for teams, Paper stands tall as the winner in this regard.

Versus Microsoft OneNote

OneNote lets you create notebooks. Inside each notebook, you’ve got sections to create text, audio, and image notes. You can also use tags to organize similar notes across all notebooks. Paper, as has been stated, uses a folder system.

OneNote crushes Paper in the formatting department, utilizing a ribbon-style interface not unlike Google Docs. With Paper, all you’ll get is the minimalistic pop-up with limited options. This is said to keep the UI uncluttered and more approachable, but it could do with a few more options.

Paper does not have these things. However, Paper is still better for collaboration needs. For a digital notebook that has a deep integration with Microsoft Office Suite, OneNote is your definitive option.

Who Is Dropbox Paper For?

Creators, collaborators, and presenters can all benefit from Dropbox Paper, albeit in small doses. It appears as an endless sheet of white paper and provides a large workspace for brainstorming and embedding varying forms of rich media including Trello, YouTube, Spotify, and Vimeo.

You’ll not only be able to add media but also make it interactive as well. This means you can use Dropbox Paper to create lesson plans for students or video and audio presentations for employees, and share a copy with every participant.

One of the cooler features of Paper that it has over its competitors is the checklist block. This feature allows you to create tasks, assign them to contributors, set a due date, and check them off as completed. It can be a slightly wonky feature as the tasks only appear for those they have been assigned to even though everyone is able to see the due date.

You can add Trello cards to Paper that will update in the document as they are updated on Trello. Any organization currently using this service may find this more beneficial to that of the checklist block.

Semicolon In Python: What Does It Do? Should I Use It?

You can use a semicolon in Python to put multiple statements on one line. The semicolon terminates the line of code and starts a new one.

Remember, you shouldn’t use semicolons in your Python code even though it’s possible!

Here’s an example of an expression where three separate lines of code are placed on the same line separated by semicolons.

print("Hello."); print("It is me."); print("How do you do?")


Hello. It is me. How do you do?

In Python, the semicolon acts as a statement delimiter. The Python interpreter knows that the statement ends after the semicolon and a new one begins.

When Use Semicolon in Python?

Semicolons offer a smooth landing for those with backgrounds in C or C++. This is because you can freely add semicolons at the end of each line in Python. But remember that Python doesn’t require using semicolons and you almost never see it in use.

Later on, you’ll learn why using semicolons is bad and creates hard-to-read code that is tricky to manage and understand. Before that, let’s take a look at some rare scenarios in which you might need a semicolon in Python.

Use Case 1: Running Shell Scripts

A great use case for semicolons in Python is when you need to run a short Python script from the shell.

For example, you can open up your command line window and run the following command:

$ python -c 'for i in range (4): print ("Hi") ; print(f"The number is {i}")'

This results in the following:

Hi This is the number 0 Hi This is the number 1 Hi This is the number 2 Hi This is the number 3

As you might expect, adding the statements in the same line is the only easy way to run a Python script like this on the shell window. This is why it’s handy to have a semicolon in Python as an option.

Use Case 2: Suppressing Output in Jupyter Notebook

If you work with an environment like Jupyter Notebook, you may have noticed that the last expression of your script prints the return value. Sometimes, this can be annoying if you don’t need to see the return value.

%matplotlib inline import random import pandas as pd dat = [random.gauss(10, 2) for i in range(150) ] df = pd.DataFrame( { 'C': dat} ) axis = df.C.hist() axis.set_title('Histogram', size=10)


Notice how it shows a print Text(0.5, 1.0, ‘Example Data’) before the example histogram. This is the return value of the axis.set_title(‘Example data’, size=15) function call at the last line. If you don’t want to see this, you need to suppress the function call with a semicolon.

axis.set_title('Example Data', size=15);

Now the result looks less annoying as there are no random prints before the plot.

Stop Using Semicolons in Python

If you have a background in JavaScript, C++, or C, you might be familiar with adding semicolons to each line of code to terminate statements.

In Python, you also have the option to terminate code lines with semicolons. However, this is not mandatory like in C or C++. As a matter of fact, you should stay away from using semicolons in Python.

The reason why semicolons are bad in Python is that they are not Pythonic.

If you force multiple statements on the same line, it only makes the code harder to read.

For example, let’s create a simple piece of code with some variables and prints:

temperature = 45 cold = False if temperature < 50: cold = True print('Its a cold day') print('I need more clothes') print(f'cold={cold}') print('Status changed')

This code expands to multiple lines and is readable (even though it doesn’t do anything particularly smart).

Now, let’s delete some line breaks with semicolons in the above example:

temperature = 45; cold = False if temperature < 50: cold = True; print('Its a cold day'); print('I need more clothes') print(f'cold={cold}');print('Status changed')

This piece of code looks terrible and unreadable.

To develop programs at scale, you need to write code that is easy to read. Combining expressions that belong to their own lines into the same line makes no sense. It only saves you lines but makes the code so much harder to read and maintain.


Today you learned what a semicolon does in python.

The semicolon delimits statements. This makes it possible to add multiple statements in one line by semicolon-separating them.

But using semicolons to add multiple statements on the same line is highly against best practices. Adding multiple expressions in the same line makes the code less readable and harder to maintain.

Unless you’re suppressing Jupyter Notebook prints or running a shell script with multiple expressions, you should stay away from the semi-colon in Python.

Thanks for reading. I hope you enjoy it.

Happy coding!
