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 static method is as a normal function. Only has the name related to the class. So that it cannot access the class variable and instance variable. You can call the function viaClassName.method_name Magic method And there is a special method called the magic method. The magic method is...
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.
【摘要】 So what is the difference between the Instance method, the Class method and the Static method? Instance methodThe normal method is defined with self as the first parameter. And it can only be calle... So what is the difference between the Instance method, the Class method and the...
