Counting word frequency and making a dictionary from it

Question

I want to take every word from a text file, and count the word frequency in a dictionary.

Example: \'this is the textfile, and it is used to take words and co

Answer 1

The following takes the string, splits it into a list with split(), for loops the list and counts the frequency of each item in the sentence with Python's count function count (). The words,i, and its frequency are placed as tuples in an empty list, ls, and then converted into key and value pairs with dict().

sentence = 'this is the textfile, and it is used to take words and count'.split()
ls = []  
for i in sentence:

    word_count = sentence.count(i)  # Pythons count function, count()
    ls.append((i,word_count))       


dict_ = dict(ls)

print dict_

output; {'and': 2, 'count': 1, 'used': 1, 'this': 1, 'is': 2, 'it': 1, 'to': 1, 'take': 1, 'words': 1, 'the': 1, 'textfile,': 1}
