- Parameters
lines (list or iterator of strings) – Input data in multiline adjlist format
create_using (NetworkX graph constructor, optional (default=nx.Graph)) – Graph type to create. If graph instance, then cleared before populated.
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.
- Returns
G – The graph corresponding to the lines in multiline adjacency list format.
- Return type
NetworkX graph
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]
