Communities¶
Functions for computing and measuring community structure.
The functions in this class are not imported into the toplevel
networkx
namespace. You can access these functions by importing
the networkx.algorithms.community
module, then accessing the
functions as attributes of community
. For example:
>>> from networkx.algorithms import community
>>> G = nx.barbell_graph(5, 1)
>>> communities_generator = community.girvan_newman(G)
>>> top_level_communities = next(communities_generator)
>>> next_level_communities = next(communities_generator)
>>> sorted(map(sorted, next_level_communities))
[[0, 1, 2, 3, 4], [5], [6, 7, 8, 9, 10]]
