is_weakly_connected

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 – True if the graph is weakly connected, False otherwise.
Return type:bool
Raises:NetworkXNotImplemented: – If G is undirected.

Notes

For directed graphs only.
