Difference Between Class Method And Static Method In Python
In Python, a class method is a method bound to a class rather than an instance, and it automatically receives the class itself as the first argument. On the other hand, a static method is a method bound to a class but does not receive the class or instance automatically as the first argument. Class methods are typically used when the method needs to access or modify the class itself, while static methods are useful for grouping utility functions related to the class but do not need access to the class or its instances.

1 - In Python, class methods and static methods are both alternative ways of defining methods in a class to perform specific tasks.
2) A class method is a method that operates on the class itself rather than on instances of the class. It takes the class (cls) as the first argument, allowing it to access and modify shared data across all instances of the class.
3) On the other hand, a static method is a method that doesn't have access to the class or instance and behaves like a regular function defined within the class. It is used when the method is not dependent on class or instance variables.
4) Class methods are defined using the @classmethod decorator above the method definition, and they can access and modify class variables.
5) Static methods are defined using the @staticmethod decorator above the method definition, and they do not have access to class variables.
6) Class methods are commonly used to create factory methods or alternative constructors for the class and manipulate class level attributes.
7) Static methods are typically used when a method doesn't require access to class or instance variables but is related to the class in some way and logically belongs in the class.
8) Class methods can access any attribute or method of the class by using the cls parameter, making them more versatile for class operations.
9) Static methods, being independent of class instances, are often used for utility functions that are related to the class but don't require access to class or instance data.
10) In summary, class methods are used when the method needs to access or modify class level data, while static methods are used for standalone methods that are logically related to the class but do not require access to class specific data.
