14.7.3. networkx.readwrite.graphml.write_graphml¶

networkx.readwrite.graphml.write_graphml(G, path, encoding='utf-8', prettyprint=True, infer_numeric_types=False)[source]¶

Write G in GraphML XML format to path

Parameters:

G : graph A networkx graph infer_numeric_types : boolean Determine if numeric types should be generalized despite different python values. For example, if edges have both int and float ‘weight’ attributes, it will be inferred in GraphML that they are both floats (which translates to double in GraphML). path : file or string File or filename to write. Filenames ending in .gz or .bz2 will be compressed. encoding : string (optional) Encoding for text data. prettyprint : bool (optional) If True use line breaks and indenting in output XML.

Notes

This implementation does not support mixed graphs (directed and unidirected edges together) hyperedges, nested graphs, or ports.

Examples

>>> G=nx.path_graph(4)
>>> nx.write_graphml(G, "test.graphml")
