is_weakly_connected

is_weakly_connected(G)

Test directed graph for weak connectivity.

A directed graph is weakly connected if and only if the graph is connected when the direction of the edge between nodes is ignored.

Note that if a graph is strongly connected (i.e. the graph is connected even when we account for directionality), it is by definition weakly connected as well.

Parameters

GNetworkX Graph

A directed graph.

Returns

connectedbool

True if the graph is weakly connected, False otherwise.

Raises

NetworkXNotImplemented

If G is undirected.
