Capital letter word count python

Question

Right now my code prints how many times every word is used in the txt file. I'm trying to get it to ONLY print the top 3 words used with capital letters within the txt file...

file=open("novel.txt","r+")
wordcount={}
for word in file.read().split():
    if word not in wordcount:
        wordcount[word] = 1
    else:
        wordcount[word] += 1
for a,b in wordcount.items():
    print (b, a)

First you want to limit your result to only capitalized words using str.istitle() :

file=open("novel.txt","r+")
wordcount={}
for word in file.read().split():
    if word.istitle():
        if word not in wordcount:
            wordcount[word] = 1
        else:
            wordcount[word] += 1
for a,b in wordcount.items():
    print (b, a)

Then sort the results using sorted() and print out the first three:

file=open("novel.txt","r+")
wordcount={}
for word in file.read().split():
    if word.istitle():
        if word not in wordcount:
            wordcount[word] = 1
        else:
            wordcount[word] += 1

items = sorted(wordcount.items(), key=lambda tup: tup[1], reverse=True) 

for item in items[:3]:
    print item[0], item[1]

In Collections there's a Counter class. https://docs.python.org/2/library/collections.html .

cnt = Counter([w for w in file.read().split() if w.lower() != w]).most_common(3)
