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 ...
The__del__method is the destructor of the class. It is used to destroy the instance of the class. And it will be called automatically when the instance is destroyed. (But there still exists some problems, if the interpreter is terminated, but the instance is not destroyed, the destructor ...

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.
2. 静态方法(Static method)Static methods are a special case of methods. Sometimes, you'll write code that belongs to a class, but that doesn't use the object itself at all. For example:静态方法是特殊的方法。有时,你想在类中写一些代码,却不去使用和这个类任何相关的东西。例如: ...
Any method we create in a class will automatically be created as an instance method unless we explicitly tell Python that it is a class or static method. Instance method in Python Define Instance Method Instance variablesare not shared between objects. Instead, every object has its copy of the...
In Python, any instance method is really a static method with a self parameter, and the object you call the method on is implicitly passed first to this method. For example: class User: def __init__(self, name): self.name = name def say_...
