Hi wyz23x2, did you do that from a clean interpreter?

_ is set to the last non-None result: https://github.com/python/cpython/blob/dd8a93e23b5c4f9290e1cea6183d97eb9b5e61c0/Python/sysmodule.c#L690-L696

So what you are seeing is that (None and True) is None, but _ is set to some value that you got from a previous input.

I think the component for this report is "Interpreter core".
