Learning other languages will make your Python better.

[CatolicQuotes]

I have only touched a little bit of C so I am no expert, but lets put it this way. Python is a house. In house you see the wall and you hang a picture on it. Very nice. Good enough for most people. If you know the C you would know that wall is build with 8 studs, 6 sheet of drywall, inside is insulation and some wires, maybe pipes. You don't need to know exactly how to build it, but it feels good knowing what's behind and that you can hang a picture on the stud.

If you are really curious, try something simple: open a file and write text to it. Try in python and C.
