write_sparse6(G, path, nodes=None, header=True)¶
Write graph G to given path in sparse6 format. :param G: :type G: Graph (undirected) :param path: 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
NetworkXError– If the graph is directed
>>> G = nx.Graph([(0, 1), (0, 1), (0, 1)]) >>> nx.write_sparse6(G, 'test.s6')
The format does not support edge or node labels.
