They would better be called classes. Every thing is Python is an instance of a class. 'Iterator' and 'context manager' are protocols that multiple classes can follow, not classes themselves.
Am I getting anything wrong here ? I'm a bit confused about it. I have never seen so many types in the few programming languages I saw.
C has up to 8 integer types, Python 3 just 1. Most of the above are structures in C, which may or may not by typedef-ed, or classes in C++. If you counted all the structures and classes that come with C or C++, you would find a comparable number.
C stdlib has a pointer to file structure type, which is equivalent to Python's file class. It is true that C does not come with hashed arrays (sets) and hashed associative arrays (dicts), but they are often needed. So C programmers either reinvent the wheel or include a third-party library. C also has frame structure, but they are normally hidden. C programmers do not have easy direct access. However, virus writers learn to work with them ;-(.
