Returns True if G has no edges.

Parameters:

G (graph) – A NetworkX graph.

True if G has no edges, and False otherwise.

Notes

An empty graph can have nodes but not edges. The empty graph with zero nodes is known as the null graph. This is an $O(n)$ operation where n is the number of nodes in the graph.
