Python: Count Word Frequency

By Xah Lee. Date: .

Here's a script that computes frequency of words in file.

The input file is typicall a novel, fiction, essay, etc.

# -*- coding: utf-8 -*-
# Python

# count the occurence of words in a file
# prints words with their counts

# to use, save this file as word_freq.py, edit the line filePath, then run “python word_freq.py”

# 2006-10-27  http://xahlee.info/

import re, operator

filePath = "/Users/joe/alice.txt"

# keys are words, vals are occurance frequency
freqlist={}

inF = open(filePath,'rb')
s=unicode(inF.read(),'utf-8')
inF.close()

s=s.lower()

wordlist = re.split(r'\W',s);
for wd in wordlist:
     if freqlist.has_key(wd):
         freqlist[wd]=freqlist[wd]+1
     else:
         freqlist[wd]=1

for k,v in sorted(freqlist.iteritems(), key=operator.itemgetter(1) ,reverse=True):
    print k.encode('utf-8') + "\t" + str(v)
