When we declare a variable inside a class but outside any method, it is called as class or static variable in python. Class or static variable can be referred through a class but not directly through an instance. Class or static variable are quite distinct from and does not conflict with any other member variable with the same name. 3. Hence, in newer versions of Python, you can use the @staticmethod decorator. Use static methods to define utility methods or group a logically related functions into a class. 6. 3. In the class method compulsory, we must use the decorator @classmethod . Python is a dynamically typed language. This means that the Python interpreter does type checking only as code runs, and the type of a variable is allowed to change over its lifetime. Here are a couple of examples that demonstrate those ideas: Pickling is the process whereby a Python object hierarchy is converted into a byte stream, and unpickling is the inverse operation, whereby a byte stream (from a binary file or bytes-like object) is converted back into an object hierarchy. advantages of the Python static method If you dont need access to the attributes or methods of the class or instance, a staticmethod is better than a classmethod or instancemethod . That way it is clear (from the @staticmethod decorator) that the class and instances state is not read or modified. Static methods are general utility purpose methods which means we are not using any instance and static variables inside these methods. 4.
