You may try: import en
instead of: import nltk

You may try: en.verb.present(v) instead of: present_tense(v)

The en package is from the NodeBox English Linguistics library

Demo site: http://wnbot.com/wordnet/stackoverflow.py

Draft source code listing:

#!/usr/bin/python

import en
import sys

went = 'went'
going = 'going'
gone = 'gone'
goes = 'goes'

print "Content-Type: text/html"
print
print "<html><head><title>Stack Overflow answer</title></head><body>"
print ' The present tense of <b>',going, '</b> is <i>',en.verb.present(going),'</i><br>'
print ' The present tense of <b>',goes, '</b> is <i>',en.verb.present(goes),'</i><br>'
print ' The present tense of <b>',gone, '</b> is <i>',en.verb.present(gone),'</i><br>'
print ' The present tense of <b>',went, '</b> is <i>',en.verb.present(went),'</i><br>'
print "</body></html>"
