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

This is my solution resulting in an error. Returns 0

PS: I\'d still love a fix to my code :)

import          


        

Answer 1

word_display = ""
for letter in word:
    if letter in known:
        word_display = "%s%s " % (word_display, letter)
    else:
        word_display = "%s_ " % word_display
return word_display
