Everything that a user sees in Python is an object, such as integers, functions, dictionaries, lists, and many other entities. It is a subpart of a class. Every Python object has a type, and users can create the object types using classes. Syntax: classClass_name:#body of the class ...
Python Classes: Definition and Example A "class" in Python is a blueprint or template for creating objects. It defines a set of attributes (variables) and methods (functions) common to all objects of that class. The purpose of a class is to serve as a blueprint for creating multiple inst...

We then created a method called get_color(). Within a method in a class in Python, you want to pass in the parameter, self, into the method. self is a reference that when you name an object, it is referring to itself, one of its attributes. It's pretty self-descriptive and self-...
In the above example, it’s clear thatcircle_area()can’t modify the class or the class instance in any way. (Sure, you could always work around that with a globalvariablebut that’s not the point here.) Now, why is that useful?
