Count the Number of Vowel in Python

# Program to count the number of each vowel in a string
# string of vowels
vowels = 'aeiou'
# change this value for a different result
ip_str = 'Hello, have you tried our turorial section yet?'
# uncomment to take input from the user
#ip_str = input("Enter a string: ")
# make it suitable for caseless comparisions
ip_str = ip_str.casefold()
# make a dictionary with each vowel a key and value 0
count = {}.fromkeys(vowels,0)
# count the vowels
for char in ip_str:

if char in count:

count[char] += 1

print(count)

Output:

{'o': 5, 'i': 3, 'a': 2, 'e': 5, 'u': 3}
