Static method is similar to a class method, which can be accessed without an object. A static method is accessible to every object of a class, but methods defined in an instance are only able to be accessed by that object of a class.Static methods are not allowed to access the state of...

1. 类方法(Class Method) 2. 类实例方法(Instance Method) 3. 类静态方法(Static Method) 在Python中,类方法、类实例方法和类静态方法是与类相关联的三种不同类型的方法。 1. 类方法(Class Method): 类方法是通过装饰器@classmethod来定义的,它的第一个参数是类本身(通常被命名为"cls"),而不是实例。类方...

Static method What about staticmethod? It's pretty similar to classmethod but doesn't take any obligatory parameters (like a class method or instance method does). Let's look at the next use case. We have a date string that we want to validate somehow. This task is also logically bound ...
