code: search Pypi for all package versions

sample code to query the global Python package repository, PyPi, directly. Stack Overflow

#!/usr/bin/env python

''' -- search for package version from PyPi
# adapted from pip.commands.SearchCommand

import sys, xmlrpclib

pnames = sys.argv[1:]
if not pnames:
    sys.exit('Usage: pversions (packagename)...')

pypi = xmlrpclib.ServerProxy('')
for packagename in (pname.lower() for pname in pnames):
    print packagename,':'
    exact_hits = (
        hit for hit in{'name': packagename})
        if hit['name'].lower() == packagename
    print ', '.join( (hit['version'] for hit in exact_hits) )
