- write_sparse6(G, path, nodes=None, header=True)¶
Write graph G to given path in sparse6 format. Parameters ———- 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 ‘>>sparse6<<’ string to head of data
If the graph is directed
The format does not support edge or node labels.
Sparse6 specification: http://cs.anu.edu.au/~bdm/data/formats.txt for details.
>>> G = nx.Graph([(0, 1), (0, 1), (0, 1)]) >>> nx.write_sparse6(G, 'test.s6')
