Question

In python, why is recommended to inherit any class we make from the class object , why not directly make it as the base class??
An important thing I noticed is that the declaration __slots__ does not work if I make my class as a base class (instead as a subclass of the class object).
What other advantages/disadvantages do I have by inheriting my class from the class object?

Answer 1

In Python2, you must inherit from object in order to create a “new-style” class. Things like descriptors, super and __slots__ do not work correctly with “old-style” classes, but old-style classes remained for backwards compatibility.

In Python3, all classes are new-style classes, so inheriting from object is no longer necessary.
