how to use nltk in python

Question

i want to perform text processing on text file.

Answer 1

Can you be more specific?

Are you just curious how to split, strip, and join values? Or something to do with reading or writing a text file?

Answer 2

I want to perform tokenize, stemming,parsing on text file and extract noun phrases from sentence..
many times tried to import nltk but found error that " no module name is nltk"

thanks for your response.

Answer 3

The instructions for this is actually on the front page of nltk.org

"
>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning ... Arthur didn't feel very good. """
>>> tokens = nltk.word_tokenize (sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning', 'Arthur', 'did', "n't" 'feel', 'very', 'good', "."]
"

As for the import error, you'll have to ask on their discussion board to troubleshoot your problem.
