remove nodes directed networkx code example

Example: networkx remove nodes with degree

import networkx

G1 = networkx.Graph()
G1.add_edges_from([('a','b'),('b','c'),('c','e'),('c','d'),('c','f'),('c','g')])
to_be_removed = [x for  x in G1.nodes() if G1.degree(x) <= 1]

for x in to_be_removed:
    G1.remove_node(x)

print(G1.edges())
