U ?hc@sdZdgZddZdS)z2Helper functions for community-finding algorithms. is_partitioncsRt|tst|}fdd|D}tt|koLtdd|DkSS)aReturns *True* if `communities` is a partition of the nodes of `G`. A partition of a universe set is a family of pairwise disjoint sets whose union is the entire universe set. Parameters ---------- G : NetworkX graph. communities : list or iterable of sets of nodes If not a list, the iterable is converted internally to a list. If it is an iterator it is exhausted. cs"h|]}|D]}|kr |q qSr).0cnGr_/var/www/html/venv/lib/python3.8/site-packages/networkx/algorithms/community/community_utils.py s zis_partition..css|]}t|VqdS)N)len)rrrrr szis_partition..) isinstancelistr sum)rZ communitiesZnodesrrrrs N)__doc____all__rrrrrs
