Top 10 courses to learn Python online

Why should you learn Python?

Whether it's your first language or your third, Python is a great language to learn. Python is commonly recommended for beginner programmers as a result of its relatively lax syntax rules and high degree of readability. That said, Python is far from just a starter language, and it occupies one of the top spots for most commonly used languages by software developers around the world. According to the 2022 Stack Overflow developer survey, 58% of people learning to code report using Python.

It is important to note that when we say Python, we're referring to Python 3, the current version of the language. If you're just starting out, there is no reason to go back and learn Python or Python 2 as they are largely out-of-date. The only reason you may need to learn Python 2 is if you are working on older systems that were built using Python 2 and need to be updated to Python 3.

Python is a versatile general-purpose language. Python has been expanded for several use cases, with plenty of libraries like:

  • Pandas, for data science
  • Scikit Learn, for machine learning
  • SciPy, for scientific computing As well as web frameworks like:
  • Flask and Django, for web development

In this article we will go over our picks for Educative's best courses to learn Python online. These range from general, beginner courses to specialized intermediate courses that build on a prior foundation of Python basics. Every course on this list is text-based and has periodic interactive quizzes. Additionally, no third party coding environment is required: all code can be executed right in your browser.

We know that it is easy to get overwhelmed with the myriad of coding courses and learning tools available online. It can be difficult to know where to start or how to keep up with programming trends if you're just sifting through the Internet. We aim to do learners a service by telling you exactly where to find trusted, battle-tested learning tools depending on your individual goals.

We'll break down each course with a brief synopsis, a list of key concepts, prerequisites, who the course is for, and the main learning goal or outcome. Afterwards, we've included an overview of our comprehensive learning paths that compile content from multiple different courses.

We'll go over:
