The private method and attribute can be accessed by the instance internally, so you can use the public method to access them indirectly. In deed, there is no real private method inPython, it just converts the method name to_ClassName__method_name()or_ClassName__attribute_name. You can use...
The add method is a static method defined using the @staticmethod decorator. It does not require an instance of the class to be called and can be accessed directly using the class name. Static Methods in Utility ClassesThis example demonstrates how static methods are commonly used in utility ...

Unlike instance methods and class methods, static methods do not have any special first parameter. They can have regular parameters, but the first parameter has no special significance. So, when a static method is called, Python does not send the class object or the instance object as the ...
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.
