For a time on Reddit (some years ago when I still used it) there was a trend of finding the worst way of implementing is_even(x: int) -> bool. My contribution to that was a function that ran Ackerman(x,x) flipping a Boolean at every iteration, and check if it was true or false at the end.
That’s also slower than most of the stuff you could come up with, it is so slow that there is no hyperoperation fast enough to describe it. There were other approaches that were almost worse though, like “the function is a switch-case that returns false by default. As complaint tickets are opened, more cases get added to the switch-case”
the function is a switch-case that returns false by default. As complaint tickets are opened, more cases get added to the switch-case”
Oh if that is acceptable, then my secondary idea of using an API call for this should work too. I thought that it would have to be guaranteed to be correct (as long as you don’t reach a stack overflow or something)
It never occurred to me that you could assign fields to a function. I mean, it totally makes sense considering that functions are objects in Python. It just never occurred to me that this is a thing one can do. Crazy.
Please don’t do that, I was stupid when I wrote that. But still, in very dynamic languages like python or js everything is an object, including functions, so you can just do object stuff on them.

I would love to see the implementaion.
The implementation is not very exciting, I capture a variable in python. It could have been done more cleanly.
The proof is this. But, I could have made mistakes, it was many years ago.
Note that in python you’ll never be able to run
is_even(5)the stack cannot handle itEdit: daaaamn, that variable is ugly as hell. I would never do things like that now.
That’s , uh…
Yeah. Cooler than anything I could’ve achieved for purposefully bad is_even
My first idea of a purposefully bad is_even is this:
def is_even(i): return True if i == 0 else not is_even(abs(i)-1)But I’m sure I could come up with worse given enough time.

I wasn’t going to, and after I saw it it totally makes sense that it’s possible, it just never occurred to me.
I guess this could be used like static variables inside functions in c. So scope-limited global variables. Not a good design choice in most cases.
