-------------------------------------------------------------------
Here's the one we have in the DataStax docs. It could stand a little
improvement, e.g. adding a help section, being more graceful w/ non integer
input.
{code}
#! /usr/bin/python
import sys
if (len(sys.argv) > 1):
num=int(sys.argv[1])
else:
num=int(raw_input("How many nodes are in your cluster? "))
for i in range(0, num):
print 'token %d: %d' % (i, (i*(2**127)/num))
{code}
