CntNonZNodes

CntNonZNodes()

A graph method that returns the number of nodes in a graph with degree greater than 0.

Parameters:

• None

Return value:

• int

  The number of nodes in a graph with degree greater than 0.

The following example shows how to calculate the number of non-zero nodes in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.TNGraph, 100, 1000)
Count = Graph.CntNonZNodes()
print("Directed Graph: Count of nodes with degree greater than 0 is %d" % Count)

UGraph = snap.GenRndGnm(snap.TUNGraph, 100, 1000)
Count = UGraph.CntNonZNodes()
print("Undirected Graph: Count of nodes with degree greater than 0 is %d" % Count)

Network = snap.GenRndGnm(snap.TNEANet, 100, 1000)
Count = Network.CntNonZNodes()
print("Network Graph: Count of nodes with degree greater than 0 is %d" % Count)
