DelNodes (SWIG)ΒΆ

DelNodes(Graph, NIdV)

Removes the nodes contained in the vector NIdV from Graph.

Parameters:

  • Graph: graph (input)

    A Snap.py graph or a network.

  • NIdV: TIntV, vector of ints (input)

    A vector of node ids to be deleted from Graph.

Return value:

  • None

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

import snap

V = snap.TIntV()
for i in range(10):
    V.Add(i)

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

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

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