Write a program to count the number of each vowel in a given string.

Solution
input_string = input("Enter a string: ")
vowel_count = {'a': 0, 'e': 0, 'i': 0, 'o': 0, 'u': 0}
input_string = input_string.lower()

for char in input_string:
    if char in vowel_count:
        vowel_count[char] += 1

print("Vowel counts:", vowel_count)
Output
Enter a string: The quick brown fox jumps over the lazy dog.
Vowel counts: {'a': 1, 'e': 3, 'i': 1, 'o': 4, 'u': 2}
