networkx.connected_component_subgraphs¶

networkx.connected_component_subgraphs(G, copy=True)[source]¶

Generate connected components as subgraphs.

Parameters:	G : NetworkX graph An undirected graph. copy: bool (default=True) If True make a copy of the graph attributes
Returns:	comp : generator A generator of graphs, one for each connected component of G.
Raises:	NetworkXNotImplemented: If G is undirected.

Notes

For undirected graphs only. Graph, node, and edge attributes are copied to the subgraphs by default.

Examples

>>> G = nx.path_graph(4)
>>> G.add_edge(5,6)
>>> graphs = list(nx.connected_component_subgraphs(G))

If you only want the largest connected component, it’s more efficient to use max instead of sort:

>>> Gc = max(nx.connected_component_subgraphs(G), key=len)
