Parameters:

Examples

You can read a graph6 file by giving the path to the file:

>>> import tempfile
>>> with tempfile.NamedTemporaryFile() as f:
...     _ = f.write(b">>graph6<<A_\n")
...     _ = f.seek(0)
...     G = nx.read_graph6(f.name)
>>> list(G.edges())
[(0, 1)]

You can also read a graph6 file by giving an open file-like object:

>>> import tempfile
>>> with tempfile.NamedTemporaryFile() as f:
...     _ = f.write(b">>graph6<<A_\n")
...     _ = f.seek(0)
...     G = nx.read_graph6(f)
>>> list(G.edges())
[(0, 1)]
