Generate weakly connected components of G.
Parameters: G (NetworkX graph) – A directed graph Returns: comp – A generator of sets of nodes, one for each weakly connected component of G. Return type: generator of sets
Generate a sorted list of weakly connected components, largest first.
>>> G = nx.path_graph(4, create_using=nx.DiGraph()) >>> G.add_path([10, 11, 12]) >>> [len(c) for c in sorted(nx.weakly_connected_components(G), ... key=len, reverse=True)] [4, 3]
If you only want the largest component, it’s more efficient to use max instead of sort.
>>> largest_cc = max(nx.weakly_connected_components(G), key=len)
For directed graphs only.
