Sorry about how amateur this is, but what does the '!' do in python? I see it all the time and wonder.

All the time? Where do you see it? I can only think of one place where it occurs often:

a != b

meaning a not equal to b.

Just looking through the snippets and posts I'll see it.

You might also see it in the sh-bang:


#!/usr/bin/python


There, it tells the shell to interpret this with python (and not with your default shell).
