generate_edgelist
(G, delimiter=' ', data=True)[source]¶ Generate a single line of the graph G in edge list format.
- Parameters
G (NetworkX graph)
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
>>> G = nx.lollipop_graph(4, 3) >>> G[1][2]["weight"] = 3 >>> G[3][4]["capacity"] = 12 >>> for line in nx.generate_edgelist(G, data=False): ... print(line) 0 1 0 2 0 3 1 2 1 3 2 3 3 4 4 5 5 6
>>> for line in nx.generate_edgelist(G): ... print(line) 0 1 {} 0 2 {} 0 3 {} 1 2 {'weight': 3} 1 3 {} 2 3 {} 3 4 {'capacity': 12} 4 5 {} 5 6 {}
>>> for line in nx.generate_edgelist(G, data=["weight"]): ... print(line) 0 1 0 2 0 3 1 2 3 1 3 2 3 3 4 4 5 5 6
