All falsey values for pattern are equally dangerous as "".

Python and mypy are both smart enough to figure out without the type hint that if len(pattern) is assigned to m then m is an int.

Suggested change
m: int = len(pattern)
if m == 0:
return 0
if not pattern:
return 0
m = len(pattern)

strings/bitap_string_match.py Outdated
