def count_vowels(message):

""" consumes a string and returns the number of vowels in that string"""

letter_list = list(message.lower())

"*** YOUR CODE HERE ***"

ans=0

vowel_list=['a','e','i','o','u']

for letter in letter_list:

if letter in vowel_list:

ans+=1

return ans

x=str(input("Enter String: "))

y=count_vowels(x)

print("the number of vowels in given string = "+str(y))
