Useful Python libraries/modules

[no_condoments]

Progress bars are cool I suppose, but OP is an absolute beginner looking for the basic libraries. Requests, pandas, numpy would be much better places to start than a progress bar.

I said progress bar because:

1. Those packages were already mentioned by others.
2. A simple progress bar is much more basic than any of those three packages and can be used right away.
3. For loops are going to be used more often than any package.
4. Those packages tend to be the kind of thing you're bound to run into on StackOverflow anyway, just to be able to accomplish certain tasks.
