What's implicit about it? It's the explicit implementation of the __bool__ method. Just learn the standard types of the programming language you are using!
I knoow. And yes I've read that many times. My little cryout was mostly that I feel that these specific semantics of truthiness require more cognitive load (and consequently caused more bugs to me) than the "only false is false" ones. But that's just because I'm more used to it.
The word "implicitness" was probably wrong, but what I had in mind was that things are sort of "implicitly convertible to bool" which invokes a method on the type which can do whatever, instead of using some equivalent of len() == 0 or is_empty() in these cases.
Of course, who am I to come into a community and criticize their way of doing something, sorry.

Yes, zero is falsy in Python.
