write_graph6(G, path, nodes=None, header=True)¶
Write a simple undirected graph to path in graph6 format.
- G (Graph (undirected)) –
- path (file or string) – File or filename to write.
- nodes (list or iterable) – Nodes are labeled 0...n-1 in the order provided. If None the ordering given by G.nodes() is used.
- header (bool) – If True add ‘>>graph6<<’ string to head of data
NetworkXError– If the graph is directed or has parallel edges
>>> G = nx.Graph([(0, 1)]) >>> nx.write_graph6(G, 'test.g6')
The format does not support edge or node labels, parallel edges or self loops. If self loops are present they are silently ignored.
