Or if you want to be able to handle large graphs efficiently, igraph
might be a good choice:

It's written in pure C, but has a Python interface and according to my
measurements, it's much faster than any other Python graph package. The
Python interface really needs some documentation, though, because now
the only way to figure things out is to call help(igraph.Graph) after
importing the module. (Or read the documentation of the C interface and
hope that the function arguments are the same :))
