Parameters ---------- G : graph A NetworkX graph Returns ------- GC : A new graph. Notes ----- Note that `complement` does not create self-loops and also does not produce parallel edges for MultiGraphs. Graph, node, and edge data are not propagated to the new graph. Examples -------- >>> G = nx.Graph([(1, 2), (1, 3), (2, 3), (3, 4), (3, 5)]) >>> G_complement = nx.complement(G) >>> G_complement.edges() # This shows the edges of the complemented graph EdgeView([(1, 4), (1, 5), (2, 4), (2, 5), (4, 5)]) c3PK|]\}}D]}||vs||k7s||fyw)N).0nnbrsn2Gs h/home/mcse/projects/flask/flask-venv/lib/python3.12/site-packages/networkx/algorithms/operators/unary.py zcomplement..'s2WWQW"Rt^qTVw!RWWs && &) __class__add_nodes_fromadd_edges_from adjacency)r Rs` rrrsA8 AQW W Hcp|jstjd|j|S)aaReturns the reverse directed graph of G.
