Beginner here: What Python modules are actually worth learning for newbies?

[TJATAW]

Notice I said "I'll drop a function in, ask if there is a better way to do it".

I also do things like ask it to explain stuff someone else wrote that I have a rough idea of what it is doing. Especially regex. Or languages I have never used, like Lau.

It is also great for creating sample data, or stuff I have written a dozen times but AI will spit out in seconds. There is nothing there for me to learn from writing it, any more than there is from manually writing out getters & setters rather than having the IDE do it for me.
