  True or false or null.

  Mathematicians didn’t know it yet, but numbers can now be even, odd or neither.

    True or false or null.

    Ah, yes, a three-state boolean.

      Even Linus Torvalds prefers an int-based truthiness to bool

    Non integers certainly aren’t even or odd, so yes?

      Yeah, I’m chalking that up to Python’s untypedness. I was going to write “integers”, but technically that function takes a “num”, whatever that is.

      For all we know, it could be a string, asking ChatGPT to hack the government. Is that even? Probably no. Or None. Or T-Rex. Without reading the entire function, we don’t know that it’s not returning T-Rex.

      Thankfully, it doesn’t matter. Just stick the result into an if-else, then False and None will land you in the else-branch. And both True and our Truthiness-Rex will land you in the if-branch. Just as Guido intended.

      …this rant brought to you by trauma.
