Every variable in Python is actually an object. You don’t have to write object-oriented (OO) code to use Python, but the way Python is constructed encourages an OO approach.1
Object Types
All variables have a type that can be seen by using the built-in type() function.
>>> type(23)
<type 'int'>
>>> type('some more text')
<type 'str'>
>>> c=[1,2,'some more text']
