Answer the newbie what's what: I'm already confused in command lines, consoles and terminals, etc. )?

Question

Python

I study book courses, etc., and there either "go to the PC command line", then "work in the terminal that was installed with Python", then the built-in terminal in the editor, are there separate ones for git?
in general, I'm confused what's what, do these terminals have different goals or can all this be somehow combined?
and how to organize the work, what can be safely deleted, and what should be left?

Answer 1

I would just use PyCharm and its git client.
