- generate_graph6(G, nodes=None, header=True)¶
Generate graph6 format string from a simple undirected graph.
G : Graph (undirected)
nodes: list or iterable
Nodes are labeled 0...n-1 in the order provided. If None the ordering given by G.nodes() is used.
If True add ‘>>graph6<<’ string to head of data
s : string
String in graph6 format
If the graph is directed or has parallel edges
The format does not support edge or node labels, parallel edges or self loops. If self loops are present they are silently ignored.
Graph6 specification: http://cs.anu.edu.au/~bdm/data/formats.txt for details.
>>> G = nx.Graph([(0, 1)]) >>> nx.generate_graph6(G) '>>graph6<<A_'
