PrintInfo

PrintInfo(Graph, Desc, OutFNm="", Fast=True)

Prints basic Graph statistics to standard output or to a file named OutFNm. Additional extensive statistics which is computationally more expensive is computed when Fast is False.

Parameters:

  • Graph: graph (input)

    A Snap.py graph or a network.

  • Desc: string (input)

    Graph description. Do not provide an empty string “” for this parameter, it might cause your program to crash.

  • OutFNm: string (input)

    Optional file name for output. If not specified, output is printed to standard output. Do not provide an empty string “” for this parameter, it might cause your program to crash. To print to standard output on Mac OS X or Linux, provide “/dev/stdout” as a file name. This method does not work on Windows.

  • Fast: bool (input)

    Optional flag specifing whether basic (True) or extended (False) statistics should be printed. Currently, it is not possible to have extended statistics printed out to standard output on Windows, since OutFNm must be non-empty, if specified.

Return value:

  • None

The following example shows how to calculate graph statistics for random graphs of type TNGraph, TUNGraph, and TNEANet:

import snap

# print extended statistics to file 'info-pngraph.txt'
Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000)
snap.PrintInfo(Graph, "Python type PNGraph", "info-pngraph.txt", False)

# print basic statistics to file 'info-pungraph.txt'
UGraph = snap.GenRndGnm(snap.PUNGraph, 100, 1000)
snap.PrintInfo(UGraph, "Python type PUNGraph", "info-pungraph.txt")

# print basic statistics to standard output
Network = snap.GenRndGnm(snap.PNEANet, 100, 1000)
snap.PrintInfo(Network, "Python type PNEANet")
