Dear comp.lang.python,
When I asked ChatGPT how I would get the number of zero bits in a Python
integer, it spouted some nonsense about calculating it with
( n & -n ).bit_length() - 1
but that hardly seems like the best way. Specifically, I'm trying to
count the number of zero bits to the

Why can't we do that?
You /can/ ask your chatbot to generate a C extension that
