How to find the count of a word in a string

Question

I have a string "Hello I am going to I with hello am". I want to find how many times a word occur in the string. Example hello occurs 2 time. I tried this approach that only prints characters -

def countWord(input_string):
    d = {}
    for word in input_string:
        try:
            d[word] += 1
        except:
            d[word] = 1

    for k in d.keys():
        print "%s: %d" % (k, d[k])
print countWord("Hello I am going to I with Hello am")

I want to learn how to find the word count.

Answer 1

If you want to find the count of an individual word, just use count:

input_string.count("Hello")

Use collections.Counter and split() to tally up all the words:

from collections import Counter

words = input_string.split()
wordCount = Counter(words)
