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 pNoneigraph's Python interface conforms to this standard. g.to_undirected() converts g to undirected in place, and returns None.GaborOn Fri, Feb 21, 2014 at 7:07 PM, Gábor Csárdi <address@hidden> wrote:

Hello!I am trying to convert my directed graph g into an undirected graph using to_undirected().<< g = GraphBase.Read_Pajek("C:/Users/Palomino/Downloads/109Senate-Rows.net")<< g = g.to_undirected(False)<< print gNoneI don't know why it returns None. Can you help me out?What should it return? The result of the conversion is in g, it does it in place.G.Thanks!!!
