print(MyClass.my_static_method(1, 2)) 在这个示例中,我们定义了一个 MyClass 类,并使用 @staticmethod 装饰器将 my_static_method 方法定义为静态方法。然后我们可以通过 MyClass.my_static_method(1, 2) 直接调用该方法,而不需要创建 MyClass 的实例。需要注意的是,静态方法没有对类或实例进行任何修改,因...

property是Python中的一个内置装饰器,它用于创建属性并允许开发者定义特定的操作,例如获取(getter)、设置(setter)和删除(deleter)属性值的方法。这种特性使得我们能更好地管理类的属性。 1. 创建只读属性 使用property可以创建只读属性,即只允许获取值,不允许修改。 class MyClass: def __init__(self, _value): ...

After the class has been defined, you just do this to add a property to it dynamically: setattr(SomeClass, 'propertyName', property(getter, setter)) Here is a complete example, tested in Python 3: #!/usr/bin/env python3 class Foo(): pass def get_x(self): return 3 def set_x(...

3.8 < Python < 3.11 Can use both decorators together. See this answer. Python 2 and python 3 (works in 3.9-3.10 too) A property is created on a class but affects an instance. So if you want a classmethod property, create the property on the metaclass. >>> class foo(object): ......
