CntNonZNodes '''''''''''' .. function:: CntNonZNodes (Graph) Returns the number of nodes in *Graph* with degree greater than 0. Parameters: - *Graph*: graph (input) A Snap.py graph or a network. Return value: - int The number of nodes in *Graph* with degree greater than 0. The following example shows how to calculate the number of non-zero nodes in :class:`TNGraph`, :class:`TUNGraph`, and :class:`TNEANet`:: import snap Graph = snap.GenRndGnm(snap.PNGraph, 100, 1000) Count = snap.CntNonZNodes(Graph) print "Directed Graph: Count of nodes with degree greater than 0 is %d" % Count UGraph = snap.GenRndGnm(snap.PUNGraph, 100, 1000) Count = snap.CntNonZNodes(UGraph) print "Undirected Graph: Count of nodes with degree greater than 0 is %d" % Count Network = snap.GenRndGnm(snap.PNEANet, 100, 1000) Count = snap.CntNonZNodes(Network) print "Network Graph: Count of nodes with degree greater than 0 is %d" % Count
