Regular Expression for Arabic words in python 2.7

Question

I use python 2.7 and i want to find the frequencies of the words in text file , I write a code using this following expression but there is no output :

    import nltk
    import os
    import re
    import string
    path="C:\Python27\Lib"
    os.chdir(path)
    frequency = {}
    document_text = open('1.txt', 'r')
    text_string = document_text.read().lower()
    match_pattern = re.findall(r'^[\u0621-\u064A\u0660-\u0669 ]+$', 
    text_string)

    for word in match_pattern:
         count = frequency.get(word,0)
         frequency[word] = count + 1

    frequency_list = frequency.keys()

    for words in frequency_list:
         print words, frequency[words]

This is because you do not match all characters.If you remove anchors you will get a match.See demo.
