Please write complete Python code for the question below

The following will go into a file called q4.py. Write an iterator which returns words from a big file, without reading the whole file into memory. Create function named find. Popular, which accepts a text file name as parameter, and print out the list of the ten most popular words (by the number of occurrences).

Solution

To print 10 most popular words in a file:

import string

def compareItems((w1,c1), (w2,c2)):
    if c1 > c2:
        return - 1
    elif c1 == c2:
        return cmp(w1, w2)
    else:
        return 1

def find_popular(fname):
    data = open(fname,\'r\').read()
    data = string.lower(data)
    for ch in \'!\"#$%&()*+,-./:;<=>?@[\\\\]^_`{|}~\':
        data = string.replace(data, ch, \' \')
    words = string.split(data)

    counts = {}
    for w in words:
        counts[w] = counts.get(w,0) + 1

    items = counts.items()
    items.sort(compareItems)
    for i in range(10):
        print \"%-10s%5d\" % items[i]

fname = raw_input(\"Enter file path: \")
find_popular(fname)
