full_join(G, H, rename=None, None)¶
Returns the full join of graphs G and H.
Full join is the union of G and H in which all edges between G and H are added. The node sets of G and H must be disjoint, otherwise an exception is raised.
G, H (graph) – A NetworkX graph
rename (bool , default=(None, None)) – Node names of G and H can be changed by specifying the tuple rename=(‘G-‘,’H-‘) (for example). Node “u” in G is then renamed “G-u” and “v” in H is renamed “H-v”.
- Return type
The full join graph with the same type as G.
It is recommended that G and H be either both directed or both undirected.
If G is directed, then edges from G to H are added as well as from H to G.
Note that full_join() does not produce parallel edges for MultiGraphs.
The full join operation of graphs G and H is the same as getting their complement, performing a disjoint union, and finally getting the complement of the resulting graph.
Graph, edge, and node attributes are propagated from G and H to the union graph. If a graph attribute is present in both G and H the value from H is used.
