complete_bipartite_graph(n1, n2, create_using=None)[source]

Returns the complete bipartite graph K_{n_1,n_2}.

The graph is composed of two partitions with nodes 0 to (n1 - 1) in the first and nodes n1 to (n1 + n2 - 1) in the second. Each node in the first is connected to each node in the second.

  • n1 (integer) – Number of nodes for node set A.

  • n2 (integer) – Number of nodes for node set B.

  • create_using (NetworkX graph instance, optional) – Return graph of this type.


Node labels are the integers 0 to n_1 + n_2 - 1.

The nodes are assigned the attribute ‘bipartite’ with the value 0 or 1 to indicate which bipartite set the node belongs to.
