Python script to find word frequencies of a given document

Question

I am looking for a simple script that can find frequencies of words for a given document (probably by using portable stemmer).

Is there any library or simple script

Answer 1

use nltk

import nltk

YOUR_STRING = "Your words"

words = [w for w in YOUR_STRING.split()]
freq_dist = nltk.FreqDist(words)

tokens = freq_dist.keys()

#50 most frequent
most_frequent = tokens[:50]

#50 least frequent
least_frequent = tokens[-50:]
