Import Problem - Please help

[newb.py]

I am trying to learn NLP with Python and am getting the following
error when trying to do an import statement:

>>> import nltk
>>> import re
>>> from nltk_lite.utilities import re_show
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named nltk_lite.utilities

I have installed nltk already and have a problem where I need to
remove vowels from text. I think I need this module to complete it.

Any help would be much appreciated.

Thanks.
