here's your problem.  MyWord is the value that is changing in each
iteration of the loop, not word.
Change your lines to
word2=wnl.lemmatize(MyWord)
word3=proter.stem(MyWord)
and it should work fine.

You should've gotten an undefined variable exception, unless you
defined word somewhere else.

Watch those variable names!
