DelDegKNodes

DelDegKNodes(Graph, OutDegK, InDegK)

Removes all nodes of out-degree OutDegK and all nodes of in-degree InDegK from Graph.

Parameters:

• Graph: graph (input)

  A Snap.py graph or a network.

• OutDegK: int (input)

  Specifies out-degree of nodes to be removed.

• InDegK: int (input)

  Specifies in-degree of nodes to be removed.

Return value:

• None

The following example shows how to remove nodes with out-degree OutDegK or in-degree InDegK in TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 10)
snap.DelDegKNodes(Graph, 1, 1)
for NI in Graph.Nodes():
    if NI.GetOutDeg() == 1:
        print "Node %d has out-degree 1." % NI.GetId()
    if NI.GetInDeg() == 1:
        print "Node %d has in-degree 1." % NI.GetId()

UGraph = snap.GenRndGnm(snap.PUNGraph, 100, 10)
snap.DelDegKNodes(UGraph, 1, 1)
for NI in UGraph.Nodes():
    if NI.GetOutDeg() == 1:
        print "Node %d has out-degree 1." % NI.GetId()
    if NI.GetInDeg() == 1:
        print "Node %d has in-degree 1." % NI.GetId()

Network = snap.GenRndGnm(snap.PNEANet, 100, 10)
snap.DelDegKNodes(Network, 1, 1)
for NI in Network.Nodes():
    if NI.GetOutDeg() == 1:
        print "Node %d has out-degree 1." % NI.GetId()
    if NI.GetInDeg() == 1:
        print "Node %d has in-degree 1." % NI.GetId()
