The sum of all the degrees of all the vertices is equal to twice the number of edges. The degree of a vertex is odd, the vertex is called an odd vertex. In Handshaking lemma, If the degree of a vertex is even, the vertex is called an even vertex. The degree of a graph is the largest vertex degree of that graph.

WebYou will need to use Networkx's MultiGraph to allow multiple edges between two nodes. Create your graph: G = nx.MultiGraph() Then add your edges using G.add_edge().
