networkx.is_weakly_connected

networkx.is_weakly_connected(G)[source]

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.

Parameters:

G : NetworkX Graph

A directed graph.
Returns:

connected : bool

True if the graph is weakly connected, False otherwise.
Raises:

NetworkXNotImplemented:

If G is undirected.
