DelZeroDegNodes

DelZeroDegNodes()

A graph method that removes all the zero-degree nodes from a graph.

Parameters:

• None

Return value:

• None

The following example shows how to delete all zero-degree nodes from TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.TNGraph, 100, 0)
print("Number of nodes in directed graph: %d" % Graph.GetNodes())
Graph.DelZeroDegNodes()
print("Number of nodes in directed graph after delete: %d" % Graph.GetNodes())

UGraph = snap.GenRndGnm(snap.TUNGraph, 100, 0)
print("Number of nodes in undirected graph: %d" % UGraph.GetNodes())
UGraph.DelZeroDegNodes()
print("Number of nodes in undirected graph after delete: %d" % UGraph.GetNodes())

Network = snap.GenRndGnm(snap.TNEANet, 100, 0)
print("Number of nodes in network: %d" % Network.GetNodes())
Network.DelZeroDegNodes()
print("Number of nodes in network after delete: %d" % Network.GetNodes())
