Python — check if a string contains Cyrillic characters

Question

How to check whether a string contains Cyrillic characters?

E.g.

>>> has_cyrillic(\'Hello, world!\')
False
>>> has_cyrillic(\'Приве         


        

Answer 1

You could create a set containing the cyrillic letters and just check each character of the string:

cyrillic_letters = {....} # fill it with the cyrillic letters

def has_cyrillic(text):
    for c in text:
        if c in cyrillic_letters:
            return True
    return False
