Write a function `consonantCount`, `consonant_count` or `ConsonantCount` that takes a string of English-language text and returns the number of consonants in the string.
Consonants are all letters used to write English excluding the vowels `a, e, i, o, u`.
def consonant_count(s):
    return sum(c in "bcdfghjklmnpqrstvwxyz" for c in s.lower())
def consonant_count(s):
    return sum(c in "bcdfghjklmnpqrstvwxyz" for c in s.lower())
