Python is an object oriented programming language. Almost everything in Python is an object, with its properties and methods. A Class is like an object constructor, or a "blueprint" for creating objects.

Inheritance in Python can be accomplished by putting the superclass name between parentheses after the subclass or child class name. In the example code block, the Dog class subclasses the Animal class, inheriting all of its attributes.

In our example, the call x.f() is exactly equivalent to MyClass.f(x). In general, calling a method with a list of n arguments is equivalent to calling the corresponding function with an argument list that is created by inserting the method’s instance object before the first argument. In general, methods work as follows. When a non-data attribute of an instance is referenced, the instance’s class is searched.

For example: >>> raise NameError('HiThere') Traceback (most recent call last): File "<stdin>", line 1, in <module> raise NameError('HiThere') NameError: HiThere · The sole argument to raise indicates the exception to be raised. This must be either an exception instance or an exception class (a class that derives from BaseException, such as Exception or one of its subclasses).

September 10, 2025 - Methods are functions that define the behaviour of the class. Attributes can be accessed using the dot . operator (e.g., MyClass.my_attribute). The syntax of a Python Class includes the Python keyword'class', class name, and class body.

October 23, 2020 - In this example, you will create an empty class Employee. Then you will create an object emp of the class Employee by calling Employee(). Try printing the .name attribute of emp object in the console. What happens? # Create an empty class Employee class Employee: pass # Create an object emp of class Employee emp = Employee() Try it for yourself.
