Anyone who follows computer programming languages knows that Python is moving forward at a tremendous pace. Back in June 2019, TIOBE noted that “if Python can keep this pace, it will probably replace C and Java in 3 to 4 years time, thus becoming the most popular programming language of the world.” 

Fast forward to 2021 and Python is currently at the second position with a rating of 11.84%, and is well-positioned to surpass C to establish itself as the No. 1 programming language amongst developers!

What’s noteworthy is that Python’s ratings have significantly grown between this period — so much that it won the TIOBE programming language of 2020 award due to its rising popularity.

In this article, we deep-dive into Python and bring you a comprehensive Python syntax cheat sheet so you can brush up on important concepts of Python. It can work as a quick reference for both beginners and advanced developers. 

So, let’s get started!
