Everything is an object in python - object class and type class

[Eddilbert Macharia]

Thank you all who have taken there time to assist me.
Special thanks to Steven D'Aparo even though you didn't have two you have taken you time to go into details.

I think i kind of understand now. 

Instead of python having data types like int, string, e.t.c it has two primitive types which are class type and class object which are created by python interpreter during its setup .using this two classes python is able to create some more data types

In some context type means the data type an object is e.g. an int,string e.t.c.

In the new class style, type and class sort of mean the same thing.

**type type is used to create new types when used as a metaclass 
**type object is used to provide some default behavior and attributes to this types through inheritance

The interpreter makes sure of the following 

** The type type inherits from data type object which makes the following statements are true

>>> issubclass(type,object)
True # type inherits object as its parent

>>> isinstance(type,object) 
True # because of the inheritance 

>>> type.__bases__ 
(<class 'object'>,) # because of the inheritance 

>>> isinstance(type,type) 
True # because metaclass type was used to create this data type type

** The type object is created using the type type i.e. type object is an instance of type type. The type object does not subclass i.e. inherit from any other types. 

>>> isinstance(object,type) 
True # because metaclass type was used to create this object

>>> issubclass(object,type)
False # because object does not inherit from any other class

>>> object.__bases__
() # because object does not inherit from any other class
