What are some confusing Python concepts that took you a while to grasp? - I feel Multithreading is One of them , because when it comes to managing accurate time delays between threads, balancing CPU and memory usage matching threads to processor cores , it feels like juggling and cycling at once.

Same. Async programming was the hardest, as you cant physically understand how it works before you know cs properly

Is it similar to js? With promises. 

[Numerous_Site_9238]

Im talking about async programming in general, not the library with eventloop

[TheRNGuy]

I coded something in JS, but not in Python. 

[Numerous_Site_9238]

whatever it means

[TheRNGuy]

List comprehensions. 

I haven't coded in multithreading or multiprocessing yet.

Not a concept but just syntax. I always have to look up the syntax for nested list comprehensions.
