How to check if there are letters in a string in Python?

Question

Python

I can't write a regular expression.
It is necessary to determine if there are letters (any, mostly Cyrillic) in the string.
PS Solution below in comments, thanks longclaps
print(re.search(r'[^\W\d]', 'someth111ing'))
print(re.search(r'[^\W\d]', 'something' ))
print(re.search(r'[^\W\d]', '12443'))
