Python Cheat Sheet for Leetcode - Discuss - LeetCode
June 7, 2022 - So: a[-1] # last item in the array a[-2:] # last two items in the array a[:-2] # everything except the last two items Similarly, step may be a negative number: a[::-1] # all items in the array, reversed a[1::-1] # the first two items, reversed a[:-3:-1] # the last two items, reversed a[-3::-1] # everything except the last two items, reversed Python is kind to the programmer if there are fewer items than you ask for.

Awesome Python Cheat Sheet
A warning for anyone who plans to print that two-page PDF: (1) The first time I printed it, the colored text came out as very light gray which was illegible. On my second try, I updated my print settings to "Print all text as black". The colored text then came out as medium-gray which was legible (although still lighter than I'd like). (2) The printed copy seems to be too small - on an 8.5"x11" page, it only appeared as about 6.5"x9". On my third try, I updated my print settings to increase to 125% size. The printed version then properly filled the page. (Edit to add: I just realized that my browser's print settings had been to print at 70% size, so my need to increase to 125% was maybe specific to me.) More on reddit.com

October 17, 2025 - That’s how they made the cheat sheet. ... I keep the problem links next to each use case. It makes it easier to refresh the mental connection between the concept and real-world use. Want a PDF version of my personal sheet? Maybe I’ll drop it in the next post. But honestly, building your own, the hard way, is what makes it stick. Look, I’ve been there. You're six hours into LeetCode, and you're still brute-forcing Fibonacci like it’s your sworn enemy.

I built this cheatsheet while teaching myself Python3 for various interviews and leetcoding for fun after not using Python for about a decade. This cheetsheet only contains code that I didn't know but needed to use to solve a specific coding problem. I did this to try to get a smaller high frequency subset of Python vs a comprehensive list of all methods.
