How to count the number of letters in a string without the spaces?

Question

This is my solution resulting in an error. Returns 0

from collections import Counter

import string

def count_letters(word):

    global count

    wordsList = string.split(word)

    count = Counter()

    for words in wordsList:

        for letters in set(words):

            return count[letters]

word = "The grey old fox is an idiot"

print count_letters(word)

Answer 1

Use the below code: 

def count_letters(word):

    return len(word) - word.count(' ')

Alternatively, if you have multiple letters to ignore, you could filter the string:

def count_letters(word):

    BAD_LETTERS = " "

    return len([letter for letter in word if letter not in BAD_LETTERS])
