In this tutorial, you'll compare Python's instance methods, class methods, and static methods. You'll gain an understanding of when and how to use each method type to write clear and maintainable object-oriented code.
Traditionally, decorators are placed before the definition of a function you want to decorate. In this tutorial, we'll demonstrate how to effectively use decorators in Python functions. Functions as First-Class Objects Functions in Python are first class citizens. This means that they support ...

With three arguments, return a new type object. This is essentially a dynamic form of the class statement. The name string is the class name and becomes thenameattribute. The bases tuple contains the base classes and becomes thebasesattribute; if empty, object, the ultimate base of all class...
Example 1: Create Class Method Using @classmethod Decorator To make a method as class method, add@classmethoddecorator before the method definition, and addclsas the first parameter to the method. The@classmethoddecorator is a built-in function decorator. In Python, we use the@classmethoddecorator...
