More seriously, in Python, objects are usually mutable, and their member functions modify them in place. E.g. see this:
>>> l=[1,2,3,4] >>> p=l.append([5,6,6]) >>> print p None igraph's Python interface conforms to this standard. g.to_undirected() converts g to undirected in place, and returns None.
