Question

In English there are five vowel letters in the alphabet: A, E, I, O, U. For the purposes of this exercise we won't count Y as a vowel. Write a program that takes a line of text as input and outputs the number of vowels in the words. Make sure to account for both uppercase or lowercase. You are encouraged to write functions and test code in IDLE before submitting your solutions here.

Answer 1

Answer:

s = input("Enter a sentence: ")

count = 0

for c in s:

 if "AEIOU".find(c.upper()) >= 0:

   count = count + 1

print ("There are %d vowels." % (count))

Explanation:

Just for fun, here is a super short one using regex:

import re

s = input("Enter a sentence: ")

print ("There are %d vowels." % len(re.findall("[aeiou]",s.lower())))
