- union_all(graphs, rename=(None, ), name=None)¶
Return the union of all graphs.
The graphs must be disjoint, otherwise an exception is raised.
graphs : list of graphs
List of NetworkX graphs
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”.
name : string
Specify the name for the union graph@not_implemnted_for(‘direct
U : a graph with the same type as the first graph in list
To force a disjoint union with node relabeling, use disjoint_union_all(G,H) or convert_node_labels_to integers().
Graph, edge, and node attributes are propagated to the union graph. If a graph attribute is present in multiple graphs, then the value from the last graph in the list with that attribute is used.
