Bug description:

Python 3.14.0a2+ (main, Dec 8 2024, 10:50:32) [GCC 14.2.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> bytes.fromhex('deadbee') Traceback (most recent call last): File "<python-input-0>", line 1, in <module> bytes.fromhex('deadbee') ~~~~~~~~~~~~~^^^^^^^^^^^ ValueError: non-hexadecimal number found in fromhex() arg at position 7 >>> bytes.fromhex('deadbeef') b'\xde\xad\xbe\xef'

I suggest: ValueError: fromhex() arg must be of even length.
