Big O Cheat Sheet: the time complexities of operations Python's data structures
Good for people getting into programming in general. I only have one remark: I wouldn't qualify O(n) as "Slow !" since it's still practically fast for low values of n and has the elegance of scaling linearly, which is one of the best scenarios available in the vast amount of cases a programmer will face.

r/Python on Reddit: An Interactive Cheatsheet for NumPy
December 12, 2021 -

Earlier this year I put out an interactive cheat sheet for Python. I got a lot of requests for a NumPy sheet as well. So here it is, The NumPy SpeedSheet:

https://speedsheet.io/s/numpy

The idea is simple, have a reference sheet that brings the answer to you. Use the search on top to lookup what you need and the sheet returns the answer in real time.

This sheet covers all things in the NumPy Library. Topics range from creating arrays to array manipulation to array operations with lots of examples to go along.

Here is a video tutorial I created to go along with the SpeedSheet:

https://youtu.be/0z9aaotXp4E

I'd love some feedback from any data scientists or anyone using NumPy out there for important things that are missing, or things that could be done better.

And for reference, here is the original Python SpeedSheet:

https://speedsheet.io/s/python

So play around with it and let me know what you think.

TLDR:

This is an interactive cheat sheet for the Numpy library.
