docs: S.translate(table) -> str
  
          Return a copy of the string S, where all characters have been mapped
          through the given translation table, which must be a mapping of
          Unicode ordinals to Unicode ordinals, strings, or None.
          Unmapped characters are left untouched. Characters mapped to None
          are deleted.
