title: Detecting which alphabet characters belong to in Python
body: <p>Is there a library or other simple way to detect which alphabet characters belong to in Python? I know I can use unicode code ranges for this, but if there's already a built-in way or a library or some such that provides the mappings, I'd rather not reinvent the wheel.</p>
  
  <p>Note: I'm asking about <strong>alphabet</strong> not <strong>language</strong>. Both "hello" and "hola" would map to Latin alphabet, whereas "Поиск" would map to Cyrillic. </p>
