Hello,

Why when we instance class we use parentheses but when we inheritance the class we do not even if the base class has a init_ method with more then self parameter?

Remember that our class acts like a blueprint for creating new objects? Calling a class with parentheses e.g. MyClass(args) is the way we create a new object and then use our class to add all the useful attributes to this object (this is the case for any classes using type as a metaclass).

For inheritance we’re not interested in what the the first class (the blueprint) creates, we’re interested in the class itself. So for inheritance we can just inherit directly from the class object.

Many thanks for the clear explanation.
