Basic Python Syntax Cheat Sheet
Cheat sheets can be really helpful when you’re trying a set of exercises related to a specific topic, or working on a project. Because you can only fit so much information on a single sheet of paper, most cheat sheets are a simple listing of syntax rules. This set of cheat sheets aims to remind you of syntax rules, but also remind you of important concepts as well. You can click here and download all of the original sheets in a single document.
A more recently updated version of these sheets (April 2021) is available through Leanpub. The updated version includes a sheet that focuses on Git basics, a printer-friendly b&w version of each sheet, and each sheet as a separate document. There is an option to download the fully updated set at no cost.
Python has integers and floats. Integers are simply whole numbers, like 314, 500, and 716. Floats, meanwhile, are fractional numbers like 3.14, 2.867, 76.88887. You can use the type method to check the value of an object. type(3) type(3.14) pi = 3.14 type(pi) Python Cheat Sheet 1. Primitives Numbers.

In cheat sheet python, Boolean will be taken as an integer. In a few cases, the IDE can’t be used for the purpose of debugging, where the cheat sheet python commands line window can be used to debug the python code. In such cases, the pdb module can be used which is in the built-in python library.
