remove_edge¶
- MultiDiGraph.remove_edge(u, v, key=None)¶
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 (abritrary) 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.

Examples
>>> G = nx.MultiDiGraph() >>> G.add_path([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)]) >>> G.remove_edge(1,2) # remove a single (arbitrary) edge
For edges with keys
>>> G = nx.MultiDiGraph() >>> G.add_edge(1,2,key='first') >>> G.add_edge(1,2,key='second') >>> G.remove_edge(1,2,key='second')
