vowel_consonant_count(s) that returns a tuple (vowels, consonants) counting how many alphabetic characters in s are vowels (a, e, i, o, u, case-insensitive) versus consonants. Ignore digits, spaces and punctuation entirely.s = 'Hello World'
(3, 7)
Vowels: e, o, o = 3. Consonants: H, l, l, W, r, l, d = 7. The space is ignored.
Lowercase the string first to make the vowel check case-insensitive.
Use `str.isalpha()` to skip non-letters.
