Python- Count each letter in a list of words

Question

So I have a list of words `wordList = list().\' Right now, I am counting each letter in each of the words throughout the whole list using this code

cnt = C         


        

Answer 1

An alternative approach using the iterator combinators in itertools:

import collections
import itertools

cnt = collections.Counter(itertools.chain.from_iterable(itertools.imap(set, wordList)))

Answer 2

cnt = Counter()
for word in wordList:
    lSet = set(word)
    for letter in lSet:
        cnt[letter] +=1             

Answer 3

cnt = Counter()
for words in wordList:
      for letters in set(words):
          cnt[letters]+=1

Answer 4

Add a set call:

cnt = Counter()
for word in wordList:
      for letter in set(word):
          cnt[letter]+=1

Answer 5

You can eliminate a for with update, which updates count from an iterable (in this case, a string):

from collections import Counter
words = 'happy harpy hasty'.split()
c=Counter()
for word in words:
    c.update(set(word))
print c.most_common()
print [a[0] for a in c.most_common()]

---

[('a', 3), ('h', 3), ('y', 3), ('p', 2), ('s', 1), ('r', 1), ('t', 1)]
['a', 'h', 'y', 'p', 's', 'r', 't']

Answer 6

import collections

cnt = collections.Counter('happy harpy hasty').keys()

cnt = list(cnt)

print(cnt)
