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:

lineslist or iterator of strings: Input data in multiline adjlist format
create_usingNetworkX graph constructor, optional (default=nx.Graph): Graph type to create. If graph instance, then cleared before populated.
nodetypePython type, optional: Convert nodes to this type.
edgetypePython type, optional: Convert edges to this type.
commentsstring, optional: Marker for comment lines
delimiterstring, optional: Separator for node labels. The default is whitespace.

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)
>>> list(G)
[1, 2, 3, 5]
