I know the command is nodecnt/nodeint and have tried different combinations of:

my_prob.solution.nodecnt()

but none seem to work. Does anyone know the correct syntax?

How do you know the function is nodecnt/nodeint? It actually is Cplex.solution.progress.get_num_nodes_processed():

#!/usr/bin/python

import sys
import cplex

for arg in sys.argv[1:]:
    cpx = cplex.Cplex()
    cpx.read(arg)
    cpx.solve()
    print cpx.solution.progress.get_num_nodes_processed()
