Top Python App Examples That Developers and Businesses Must Check Out

Most Popular Python App Examples

Now that we have answered the question “what is Python used for,” let us look at the best Python app examples that developers and businesses must check out. Some popular companies whose applications are developed using Python include Reddit, Instagram, Dropbox, Uber, Spotify, Netflix, Lyft, and Facebook.

1.  Reddit – A Prime Python Web Application Example

Reddit, a popular social media platform, is considered to be a source of dank memes and humorous videos; and, it is also the prime Python web application example that anyone can offer. The platform features numerous subreddits where users can communicate with a community of like-minded people and seek advice or vent out too.

According to a keynote by Steve Huffman, Reddit’s Co-Founder, he can easily understand whether a Reddit developer is writing good code or a bad one. This is because Python code has an obvious structure which makes it readable and allows other developers to easily verify whether the code is efficient or not. Python has numerous ready-to-use libraries which also helps ensure that Reddit developers can seamlessly develop the platform.

2.  Dropbox

Dropbox has a web application and also has mobile apps for iOS and Android. The popular content hosting service is capable of running on different operating systems like Mac, Windows, and Linux.

Dropbox’s current market valuation is over $9 billion, making them one of the best Python web apps examples. According to Dropbox, Python is widely used for the development of their backend services and the Dropbox desktop client app. Since the platform uses Python for both client and server sides, they reap the benefits of Python’s static type checking. The feature allows Dropbox developers to quickly verify their huge codebase and helps boost business productivity.

3.  Instagram

Unlike the other Python app examples, Instagram’s tech stack has changed over the years, but the app would not be possible without Python. Currently, Instagram has over 2.35 billion monthly active users, and was built using Django. Django is a high-level Python web framework that makes development easy and reduces the total time needed.

However, Instagram has come a long way since then, and Instagram developers have built static sort checkers that check their servers with Python. The platform’s server is majorly filled with million lines of Python code; which is why, they use type annotations to ensure their contract for Python HTTP APIs are fulfilled.

4.  Uber

When Uber was getting started, the development team had to choose between two popular programming languages – Ruby and Python. Well, the Uber development team chose Python to properly handle their frontend and backend functions which had to process numerous calculations.

If you have used the Uber app, you surely know that ride prices are based on multiple factors like traffic, demand and supply, ride duration, and weather conditions. Since the Uber backend had to handle numerous mathematical calculations at big data levels, they chose Python; after all, Python has huge computation capabilities and is easier to learn than Ruby.

To be specific, Uber uses the Tornado Python web framework to benefit from async programming. The company has also developed its own frameworks that Python accesses to render high-density data visualizations in browsers itself.

5.  Netflix

Netflix is a prime OTT platform that took the world by storm and changed the way we view movies and stream web series. The platform has a powerful recommendations and analytics engine, which provides users with great suggestions based on their watch history and other factors.

Since Python is an intuitive language, Netflix’s developers realized that the language can help them quickly solve networking issues. This is why they decided to incorporate the language and use it throughout the platform’s complete content lifecycle. Some common features of the platform realized using Python that you must check out, include ML recommendation algorithms and security tools and resources.

Here’s another interesting fact for you – Netflix’s proprietary content distribution network, widely known as Open Connect, is also built on Python. With so many features developed using Python, Netflix is certainly one of the best Python web app examples we could have found for you.

6.  Spotify

Everybody loves music and with Spotify’s music-on-the-go capabilities, the app has become the top music streaming platform. We are pretty sure that you have used Spotify on your commutes to work or tuned in to your favorite podcast; at least, we can say that we surely have!

According to a release by Spotify’s engineers, the platform’s user forecast infrastructure was developed using Python. So, you might like to thank Python for all the great music recommendations and playlists you get on Spotify!
