SaveEdgeList(Graph, Filename, Description="")

Saves lists of edges from a given graph into a file. Each line contains two columns and encodes a single edge. Creates a file named Filename.


  • Graph: graph (input)

    A graph or a network.

  • Filename: string (input)

    The name of the file to save the graph to.

  • Description: string (input)

    An optional description that will be written to the top of the file in a commented section.

Return value:

  • None

The following example shows how to save edge lists with TNGraph, TUNGraph, and TNEANet:

import snap

Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
snap.SaveEdgeList(Graph, 'mygraph.txt')

UGraph = snap.GenRndGnm(snap.PUNGraph, 100, 1000)
snap.SaveEdgeList(UGraph, 'undirected_mygraph.txt')

Network = snap.GenRndGnm(snap.PNEANet, 100, 1000)
snap.SaveEdgeList(Network, 'network_mygraph.txt')
