Almost everywhere nowadays.

Most of the doc has still not been updated since the introduction of 
newstyle classes years ago. You'll find more here:
http://docs.python.org/ref/node33.html

Nope, it's the base class for your Graph class.

parent class list in a class statement and argument list of an 
initializer are totally unrelated.

The syntax for a class statement is:
classdef  	::=  	"class" classname [inheritance] ":" suite
inheritance 	::= 	"(" [expression_list] ")"
classname 	::= 	identifier

cf http://docs.python.org/ref/class.html

Indeed. This is one of the most (in)famous Python gotchas.
