Extracting Noun Phrases From Nltk Using Python

I am new to both python and nltk. I have converted the code from https://gist.github.com/alexbowe/879414 to the below given code to make it run for many documents/text chunks. But

Solution 1:

You need to either:

• decorate each of normalize, acceptable_word, and leaves with @staticmethod, or
• add a self parameter as the first parameter of these methods.

You're calling self.leaves which will pass self as an implicit first parameter to the leaves method (but your method only takes a single parameter). Making these static methods, or adding a self parameter will fix this issue.

(your later calls to self.acceptable_word,and self.normalize will have the same issue)

You could read about Python's static methods in their docs, or possibly from an external site that may be easier to digest.
