gotcha

[micseydel]

I don't know why everyone finds bools as ints so surprising. Did no one take discrete math?

I took discrete math twice, thank you very much. Still don't understand any of it.

Really though I can see an argument being made either way. I'm used to in the statically typed languages I used booleans not being numeric (Scala / Java). As for the other side...

i bet it could be argued:  it's a feature

Yes! Python is, by convention, duck typed. It's not just dynamically typed and you're not prohibited by the language from type-checking. If it walks like a duck and quacks like a duck, why do you care if it's really a duck or not? I could design an API that does care, but such designs are not considered Pythonic. Much like "it's better to ask forgiveness than permission" being preferable "look before you leap" - there are situations when either is preferable, the culture of the language is to prefer one, and go to the other only in extraordinary circumstances.
