Question

Write function vowelCount2() that takes a string as input and counts and prints the number of occurrences of vowels in the string. Vowels are a, e, i, o, and u. Implement the code in the file lab5.py. This function is very similar to the function of the problem 4.25, but the vowel information which did not appear in the string should not be printed. The printing order of the vowels is a, e, i, o, u.

e.g.)

>>> lab5.vowelCount2(‘augustana’)

a, u, appear, respectively, 3, 2, times.

>>>lab5.vowelCount2(‘universities’)

e, i, u, appear, respectively, 2, 3, 1, times.

>>>lab5.vowelCount2(‘kkk’)

>>>lab5.vowelCount2(‘crypto’)

o, appear, respectively, 1, times

Answer 1

def vowelCount2(s):
    d = {}
    for ch in s:
        if ch in "aeiouAEIOU":
            ch = ch.lower()
            if ch not in d:
                d[ch] = 0
            d[ch] += 1
    chars = []
    values = []
    for ch, count in sorted(d.items()):
        chars.append(ch)
        values.append(str(count))
    if len(d) > 0:
        print('{}, appear, respectively, {}, times.'.format(', '.join(chars), ', '.join(values)))

# Testing the function here. ignore/remove the code below if not required vowelCount2('augustana') vowelCount2('universities') vowelCount2('kkk') vowelCount2('crypto')

a, u, appear, respectively, 3, 2, times. e, i, u, appear, respectively, 2, 3, 1, times. o, appear, respectively, 1, times.
