First, let's declare the c class, and then we will create an instance of this class called obj.

While we're talking about object types, let's take a quick break from the whole class issue and examine the types for Python objects defined in extension modules, which do not necessarily act like classes.

Line 3: Executes the class method by transporting the instance reference (obj) and the list of arguments (args).
This function returns 1 if the class object classobj1 is a subclass (derived class) of the class object classobj2.
It is important to say that when calling unbound methods (methods that are not tied to an instance) like this one, you must explicitly say that the first argument is self.
Note that the contents of the variable namespace formed by executing the commands in the class statement make up the class dictionary.

Class Instances A class instance is a Python object, and similar to every Python object, it has the following properties: identity, object type, attributes, methods, and value.
With inheritance, the derived class (also known as subclass, descendant, or child class) inherits the data members and class methods of its base (parent) class.

An Introduction to Python OOP A class defines a category of objects in terms of the data it encapsulates and the operations on the data that are allowed by the interface functions.

Python Instances Each instance defines its own namespace of data, and it inherits behavior from the class (and possible base classes) that have originated it.

An interesting detail about Python object attributes is that they don't need to be declared inside the class before they get used because they can be created dynamically.

Tip In order for Python to find your modules, the directory where you save them must be an entry of the sys.

Saying that OOP promotes data abstraction means that we define the functions that operate on the data.
