SavePajek

SavePajek(Graph, OutFNm, NIdColorH, NIdLabelH, EIdColorH)

Saves a graph in a Pajek .NET format.

Parameters:

• Graph: graph (input)

  A Snap.py graph or a network.

• OutFNm: string (input)

  Specifies output filename of Pajek formatted graph.

• NIdColorH: TIntStrH, a hash table of int keys and string values (input)

  Maps node ids to node colors. Default node color is Red.

• NIdLabelH: TIntStrH, a hash table of int keys and string values (input)

  Maps node ids to node string labels.

• EIdColorH: TIntStrH, a hash table of int keys and string values (input)

  Maps edge ids to node colors. Default edge color is black.

Return value:

• None

The following example saves the graph in the Pajek format in: TNGraph, TUNGraph, and TNEANet:

import snap

NIdColorH = snap.TIntStrH()
for i in range(100):
    if i % 2 == 0:
        NIdColorH[i] = "red"
    else:
        NIdColorH[i] = "blue"
NIdLabelH = snap.TIntStrH()
for i in range(100):
    NIdLabelH[i] = str(i)
EIdColorH = snap.TIntStrH()
for i in range(1000):
    EIdColorH[i] = "red"

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
snap.SavePajek(Graph, "Pajek_Graph1.out", NIdColorH, NIdLabelH, EIdColorH)

UGraph = snap.GenRndGnm(snap.PUNGraph, 100, 1000)
snap.SavePajek(UGraph, "Pajek_Graph2.out", NIdColorH, NIdLabelH, EIdColorH)

Network = snap.GenRndGnm(snap.PNEANet, 100, 1000)
snap.SavePajek(Network, "Pajek_Graph3.out", NIdColorH, NIdLabelH, EIdColorH)
