What is bound, unbound, and static methods in Python?

Methods in Python are like functions except that it is attached to an object.The methods are called on objects and it possibly make changes to that object. These methods can be Bound, Unbound or Static method. The static methods are one of the types of Unbound method. These types are explained in detail below.

In Python, methods are functions that are associated with an object, and they can be classified into three categories: bound, unbound, and static methods.

  1. Bound methods: Bound methods are the most common type of method in Python, and they are associated with an instance of a class. When a bound method is called, the instance of the class that it is associated with is automatically passed as the first argument (typically called "self"). This allows the method to access and modify the attributes of the instance.

  2. Unbound methods: Unbound methods are similar to bound methods, but they are not associated with an instance of a class. Instead, they are associated with the class itself. When an unbound method is called, an instance of the class must be passed as the first argument.

  3. Static methods: Static methods are methods that are not associated with either an instance of a class or the class itself. They are typically used for utility functions that do not need to access the instance or class attributes. Static methods are defined using the "@staticmethod" decorator, and they do not receive any automatic arguments related to instances or classes.

To summarize, bound methods are associated with instances of a class, unbound methods are associated with the class itself, and static methods are not associated with either.
