-
write_edgelist
(G, path, comments='#', delimiter=' ', data=True, encoding='utf-8')[source]¶ Write graph as a list of edges.
Parameters: - G (graph) – A NetworkX graph
- path (file or string) – File or filename to write. If a file is provided, it must be opened in ‘wb’ mode. Filenames ending in .gz or .bz2 will be compressed.
- comments (string, optional) – The character used to indicate the start of a comment
- delimiter (string, optional) – The string used to separate values. The default is whitespace.
- data (bool or list, optional) – If False write no edge data. If True write a string representation of the edge data dictionary.. If a list (or other iterable) is provided, write the keys specified in the list.
- encoding (string, optional) – Specify which encoding to use when writing file.
Examples
>>> G=nx.path_graph(4) >>> nx.write_edgelist(G, "test.edgelist") >>> G=nx.path_graph(4) >>> fh=open("test.edgelist",'wb') >>> nx.write_edgelist(G, fh) >>> nx.write_edgelist(G, "test.edgelist.gz") >>> nx.write_edgelist(G, "test.edgelist.gz", data=False)
>>> G=nx.Graph() >>> G.add_edge(1,2,weight=7,color='red') >>> nx.write_edgelist(G,'test.edgelist',data=False) >>> nx.write_edgelist(G,'test.edgelist',data=['color']) >>> nx.write_edgelist(G,'test.edgelist',data=['color','weight'])
