Object Class in Python

In Python, the `object` class is the cornerstone of all classes and sits at the top of the class hierarchy.

This means that every class created is inherently a subclass of `object`, and consequently, every object is an instance of `object`. Regardless of the object's type, they are all instances of `object`.

For example, create a list:

myList = [1, 2, 3]

This list is an object and is an instance of the `object` class.

print(isinstance(myList, object))

True

Even the `type` metaclass, which creates classes, is itself an instance of the base `object` class.

However, `object` has no superclasses, so it stands alone at the top of the hierarchy.

print(isinstance(type, object))

True

And naturally, the base `object` class is also an instance of itself.

print(isinstance(object, object))

True

Every object is an instance of `object`, including simple data types.

For example, assign a value to the variable n:

n = 10

The variable n is an instance of the `object` class.

print(isinstance(n, object))

True

The same principle applies when you create a custom class.

class Foo:
    pass

By accessing the __bases__ attribute of the class, you can confirm that it is derived from the `object` class.

print(Foo.__bases__)

(<class 'object'>,)

In conclusion, all classes implicitly inherit from `object`.

This means that all classes in Python, directly or indirectly, are subclasses of `object`, and therefore all objects are instances of `object`.

Some objects are "types" or "classes" if they are also subclasses of the `type` class,
