Regex functions on bytes consider zero byte as end and stop matching at that point. This is completely nonsensical since python has no problems working with zero bytes otherwise. For example: Matches as expected: re.match(b'a', b'abc') Does not match unexpectedly: re.match(b'a', b'\x00abc') |

There is no bug. The pattern b'a' matches bytes that starts with byte 97 (ord(b'a')), but b'\x00abc' starts with byte 0. |

Do note that `.match()` is constrained to match starting at the first byte. `.search()` is not (it can start matching at any position), and your example works fine if `.search()` is used instead. This is all expected, and intended, and documented. |
