Question

Write function vowelCount() that takes a string as input and counts and prints the

number of occurrences of vowels in the string.

>>> vowelCount('Le Tour de France')

a, e, i, o, and u appear, respectively, 1, 3, 0, 1, 1 times.

Answer 1

def vowelCount(s):
    a, e, i, o, u = 0, 0, 0, 0, 0  # initialize all counts to 0
    for ch in s:
        ch = ch.lower()  # take a character from string
        if ch == 'a':  # if character is a
            a += 1  # then increase a by 1
        elif ch == 'e':  # if character is e
            e += 1  # then increase e by 1
        elif ch == 'i':  # if character is i
            i += 1  # then increase i by 1
        elif ch == 'o':  # if character is o
            o += 1  # then increase o by 1
        elif ch == 'u':  # if character is u
            u += 1  # then increase u by 1
    # print result
    print("a, e, i, o, and u appear, respectively, "
          + str(a) + ", " + str(e) + ", " + str(i) + ", " + str(o) + ", " + str(u) + " times.")
