It's easy to underestimate just how much strong typing can actually hold us back in some cases, because we start thinking about what a thing is rather than what it can do. Python's take is I really don't care what it is, as long as I can interact with it according to a particular kind of set of assumptions. And that's very unique and talks like a duck and cracks like a duck. That's probably a duck. Yeah, exactly. It's special, but it works out is just something that kind of get used to definitely. All right, next one, ducks, wank, duck typing.
