16 PDF Cheat Sheets for Programmers

A couple of years ago, I fell into the habit of creating cheat sheets when exploring certain areas in the programming space. Over time, hundreds of thousands of Finxters have downloaded and used them in their own learning journeys.

However, the cheat sheets are largely scattered around many different locations on the Finxter ecosystem. And even though I share all of them with my beloved Finxter community 🥰 of ambitious coders—and subscribers to my free computer science email academy, join us! 🙂—they may not be accessible at all times by all Finxters. Time to change that!

In this article, I collect all Finxter cheat sheets and links to their PDF download locations. Feel free to share it with your hacker friends and coding mates!

Python Set Methods Cheat Sheet

Let’s move on to one of the most underutilized data structures in Python: sets. They’re far more efficient than lists—if you can handle the reduced expressiveness. You can find all set methods explained in detail in the Finxter Academy course.
