Remove all edges specified in ebunch.
ebunch (list or container of edge tuples) – Each edge given in the list or container will be removed from the graph. The edges can be:
- 2-tuples (u, v) All edges between u and v are removed.
- 3-tuples (u, v, key) The edge identified by key is removed.
- 4-tuples (u, v, key, data) where data is ignored.
- remove a single edge
Will fail silently if an edge in ebunch is not in the graph.
>>> G = nx.path_graph(4) # or DiGraph, MultiGraph, MultiDiGraph, etc >>> ebunch=[(1, 2), (2, 3)] >>> G.remove_edges_from(ebunch)
Removing multiple copies of edges
>>> G = nx.MultiGraph() >>> keys = G.add_edges_from([(1, 2), (1, 2), (1, 2)]) >>> G.remove_edges_from([(1, 2), (1, 2)]) >>> list(G.edges()) [(1, 2)] >>> G.remove_edges_from([(1, 2), (1, 2)]) # silently ignore extra copy >>> list(G.edges) # now empty graph
