networkx.MultiDiGraph.remove_edge¶

MultiDiGraph.
remove_edge
(u, v, key=None)[source]¶ Remove an edge between u and v.
 Parameters
u, v (nodes) – Remove an edge between nodes u and v.
key (hashable identifier, optional (default=None)) – Used to distinguish multiple edges between a pair of nodes. If None remove a single (arbitrary) edge between u and v.
 Raises
NetworkXError – If there is not an edge between u and v, or if there is no edge with the specified key.

remove a collection of edges
Examples
>>> G = nx.MultiDiGraph() >>> nx.add_path(G, [0, 1, 2, 3]) >>> G.remove_edge(0, 1) >>> e = (1, 2) >>> G.remove_edge(*e) # unpacks e from an edge tuple
For multiple edges
>>> G = nx.MultiDiGraph() >>> G.add_edges_from([(1, 2), (1, 2), (1, 2)]) # key_list returned [0, 1, 2] >>> G.remove_edge(1, 2) # remove a single (arbitrary) edge
For edges with keys
>>> G = nx.MultiDiGraph() >>> G.add_edge(1, 2, key='first') 'first' >>> G.add_edge(1, 2, key='second') 'second' >>> G.remove_edge(1, 2, key='second')
