Python in the Real World

Python is a high-level, multi-paradigm, and general-purpose programming language. As this definition implies, you can use Python for several purposes, from web development to data science, machine learning, artificial intelligence (AI), robotics, and more. Python’s real-world use cases are limitless.

People have successfully built many cool projects with Python. If you take a quick look at world-class companies like Google, YouTube, Meta (Facebook, Instagram), Spotify, Netflix, and others, you’ll note that they use Python to support their services and products.

Google has used Python from the start, and it has established itself as one of the tech giant’s main server-side languages. Guido van Rossum, Python’s creator, worked there for several years, overseeing the language’s development.

Instagram initially chose Python for its simplicity and the powerful Django framework, famously operating one of the largest Django deployments in the world. The platform continues to leverage Python, with Django powering its frontend servers to manage massive growth.

Spotify uses the language for data analysis and backend services. According to its team, Python’s ease of use leads to a lightning-fast development pipeline. Spotify performs a ton of analysis to give recommendations to its users, so it needs a productive tool that works well. Python to the rescue!

You’ll also find that Python has been vital for science and space exploration, with many exciting applications in robotics and hardware control. In this tutorial, you’ll explore the wide range of fields and areas where you can apply your Python skills.

Build Practical Software Products and Cool Projects

Python’s ecosystem provides a rich set of frameworks, tools, and libraries that allow you to build almost any kind of application—from web to desktop and mobile. You can even use Python to create video games.

Web Development

Web application development with Python is in high demand. In this field, you’ll find several well-established Python frameworks, libraries, and tools for developing cool web applications, APIs, and more.

Here are some of the most popular Python web frameworks:

Framework Description
Django A high-level framework that encourages rapid web application development with a clean and pragmatic design. It allows you to focus on writing your applications without reinventing the wheel.
FastAPI A fast and performant web framework for building web APIs. It’s built on top of modern Python type hinting features and enables asynchronous programming.
Flask A lightweight framework primarily focused on creating WSGI web applications. It allows you to start quickly and scale up to complex applications if needed.
Tornado A web framework and asynchronous networking library. It uses non-blocking network I/O, enabling you to write applications that can scale to tens of thousands of open connections.
