parse_multiline_adjlist¶

parse_multiline_adjlist(lines, comments='#', delimiter=None, create_using=None, nodetype=None, edgetype=None)[source]¶

Parse lines of a multiline adjacency list representation of a graph.

Parameters:

lines : list or iterator of strings Input data in multiline adjlist format create_using: NetworkX graph container Use given NetworkX graph for holding nodes or edges. nodetype : Python type, optional Convert nodes to this type. comments : string, optional Marker for comment lines delimiter : string, optional Separator for node labels. The default is whitespace. create_using: NetworkX graph container Use given NetworkX graph for holding nodes or edges.

Returns:

G: NetworkX graph The graph corresponding to the lines in multiline adjacency list format.

Examples

>>> lines = ['1 2',
...          "2 {'weight':3, 'name': 'Frodo'}",
...          "3 {}",
...          "2 1",
...          "5 {'weight':6, 'name': 'Saruman'}"]
>>> G = nx.parse_multiline_adjlist(iter(lines), nodetype = int)
>>> G.nodes()
[1, 2, 3, 5]
