I thought that the two 12 were a typo, but it seems you want to reorder the nodes inside an edge, too. Here's a fix that normalizes the edge before sorting the list of edges: edges = [sorted((ddeg[u], ddeg[v])) for u, v in G.edges()] edges.sort() for a, b in edges: print a, b, print Peter -- http://mail.python.org/mailman/listinfo/python-list
