Detecting Vowels vs Consonants In Python [duplicate]

by

Change: 

if first == "a" or "e" or "i" or "o" or "u":

to:

if first in ('a', 'e', 'i', 'o', 'u'):  #or `if first in 'aeiou'`

first == "a" or "e" or "i" or "o" or "u" is always True because it is evaluated as

(first == "a") or ("e") or ("i") or ("o") or ("u"), as an non-empty string is always True so this gets evaluated to True.

>>> bool('e')
True
