Question

This is what I have to count each word in a document:

from collections import defaultdict
word_dict=defaultdict(int)

def count_words(newstring):
    words=newstring.lower().split()
    for word in words:
        word_dict[word]+=1

When I print word_dict, I got the following results:

defaultdict(<type 'int'>, {'rate': 1, 'babo-free': 1, 'risk': 3, 'interest': 1})

I need to add each count so that total_count variable should be equal to 6.

I guess this may be too easy for many of you guys, but as a beginner, I don’t know where to start.

Answer 1

Using iteritems you can get a list of key value pairs. With that you can use a for loop to sum the numbers together.

Eg

sum = 0
for k,v in d.iteritems():
    sum += v
