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.
