Hi,

Total newbie; I kind of understand modules and I totally see why they are so useful. I guess my big question with them is how do I know what modules are out there and how do I know which modules I need for the code I'm trying to write. I.E. instead of writing a bunch of functions, code, etc, how do I know or not know if there is a module out there that does the same thing and I can just import it at the beginning.
...

How do I know which modules I need? I mean I want to move a file around a network so I import sockets; but how do I know I need to import sockets? Is there a list somewhere of all the modules and what they do?
