networkx.algorithms.bipartite.edgelist.generate_edgelist¶

generate_edgelist(G, delimiter=' ', data=True)[source]¶

Generate a single line of the bipartite graph G in edge list format.

Parameters

G (NetworkX graph) – The graph is assumed to have node attribute part set to 0,1 representing the two graph parts
delimiter (string, optional) – Separator for node labels
data (bool or list of keys) – If False generate no edge data. If True use a dictionary representation of edge data. If a list of keys use a list of data values corresponding to the keys.

Returns

lines – Lines of data in adjlist format.

Return type

string

Examples

>>> from networkx.algorithms import bipartite
>>> G = nx.path_graph(4)
>>> G.add_nodes_from([0, 2], bipartite=0)
>>> G.add_nodes_from([1, 3], bipartite=1)
>>> G[1][2]["weight"] = 3
>>> G[2][3]["capacity"] = 12
>>> for line in bipartite.generate_edgelist(G, data=False):
...     print(line)
0 1
2 1
2 3

>>> for line in bipartite.generate_edgelist(G):
...     print(line)
0 1 {}
2 1 {'weight': 3}
2 3 {'capacity': 12}

>>> for line in bipartite.generate_edgelist(G, data=["weight"]):
...     print(line)
0 1
2 1 3
2 3
