to_dict_of_dicts

to_dict_of_dicts(G, nodelist=None, edge_data=None)

Return adjacency representation of graph as a dictionary of dictionaries.

Parameters :

G : graph

A NetworkX graph

nodelist : list

Use only nodes specified in nodelist

edge_data : list, optional

If provided, the value of the dictionary will be set to edge_data for all edges. This is useful to make an adjacency matrix type representation with 1 as the edge data. If edgedata is None, the edgedata in G is used to fill the values. If G is a multigraph, the edgedata is a dict for each pair (u,v).
