DelNodes

DelNodes(NIdV)

A graph method that removes the nodes contained in the vector NIdV from a graph.

Parameters:

• NIdV: Python list or TIntV, vector of ints

  A vector of node ids to be deleted.

Return value:

• None

The following example shows how to delete nodes from TNGraph, TUNGraph, and TNEANet:

import snap

V = []
for i in range(10):
    V.append(i)

Graph = snap.GenRndGnm(snap.TNGraph, 100, 1000)
Network.DelNodes(V)
for NI in V:
    if Graph.IsNode(NI):
        print("Node %d found in graph." % NI)

UGraph = snap.GenRndGnm(snap.TUNGraph, 100, 1000)
UGraph.DelNodes(V)
for NI in V:
    if UGraph.IsNode(NI):
        print("Node %d found in graph." % NI)

Network = snap.GenRndGnm(snap.TNEANet, 100, 1000)
Network.DelNodes(V)
for NI in V:
    if Network.IsNode(NI):
        print("Node %d found in graph." % NI)
