20170530/DuckDuckGo isinstance subclass bool
Interesting find here. (A “random advertisement” at that.) According to the author, the official Python documentation is not nearly as good as that of VB.NET and JavaScript on MDN.

20170530/DuckDuckGo TypeError: type ‘bool’ is not an acceptable base type
20170530/https://stackoverflow.com/questions/10061752/which-classes-cannot-be-subclassed
bool
cannot be subclassed. Why? Bool is supposed to follow the
theory that there are only two instances of it, True and False, and
that you can’t actually create objects that are instances of bool
but have a True or False value because that would violate Python’s
bool
data type concept. According to Guido.
