Your task is simply to count the total number of lowercase letters in a string.
Examples
lowercaseCount("abc"); ===> 3
lowercaseCount("abcABC123"); ===> 3
lowercaseCount("abcABC123!@€£#$%^&*()_-+=}{[]|\':;?/>.<,~"); ===> 3
lowercaseCount(""); ===> 0;
lowercaseCount("ABC123!@€£#$%^&*()_-+=}{[]|\':;?/>.<,~"); ===> 0
lowercaseCount("abcdefghijklmnopqrstuvwxyz"); ===> 26
Solution:
def lowercase_count(string: str) -> int:
return len([i for i in string if i.islower()])
import re
def lowercase_count(string):
return len(re.findall('[a-z]',string))
