NLTK does not show ngram results from zipped file

[Mazhar Dootio]

Hellow friends;

I need your help in solving my problem of ngram results. I imported all required liberary files first than processed zipped file and than processed querty to get ngram results but it does not show results. Plz help. The coding is as below:

with zipfile.ZipFile('D:\Sindhicorpus.zip') as z:

    print (len(z.namelist()))

    for filename in z.namelist():

        if not os.path.isdir(filename):

            # read the file

            with z.open(filename, 'rU') as rf:

                line = rf.readline().decode('utf8') 

               # print(line)

(Above coding works fine)

import nltk

from nltk.collocations import *

line = ""

for val in filename:

    line += val

tokens = line.split()

bigram_measures = nltk.collocations.BigramAssocMeasures()

finder = BigramCollocationFinder.from_words(tokens)

finder.apply_freq_filter(3)

print(finder.nbest(bigram_measures.pmi, 100))

shows results only empty empty brackets  like     [ ]

Then I processed following code

from nltk import ngrams

n = 2

sixgrams = ngrams(filename.split(), n)

for grams in sixgrams:

  print(grams)

But it is also not showing any result.

plz resolve my problem.

You don’t show the details of your code, but `filename` is a string containing just the name of a zipped file. If you’re iterating over this string, you’ll just get single characters.
