Write a python program to Count Vowels, Consonants, Digits and Spaces

while True:
    s = input("\nEnter a string: ")

    vowels = consonants = digits = spaces = 0

    for ch in s:
        if ch.isalpha():
            if ch.lower() in "aeiou":
                vowels += 1
            else:
                consonants += 1
        elif ch.isdigit():
            digits += 1
        elif ch.isspace():
            spaces += 1

    print("Vowels =", vowels)
    print("Consonants =", consonants)
    print("Digits =", digits)
    print("Spaces =", spaces)

    choice = input("\nDo you want to analyze another string? (yes/no): ").lower()
    if choice != "yes":
        print("Program terminated")
        break
