现在,我们可以在MainClass中调用AnotherClass的方法。假设AnotherClass中有一个名为method的方法,我们可以这样调用: classMainClass:def__init__(self):self.another_class_instance=AnotherClass()defcall_another_method(self):self.another_class_instance.method() 1. 2. 3. 4. 5. 6. 通过以上步骤,我们成功...

类实例(Instance): 属性(Attributes):在Python中,我们可以把属性称为实例变量。属性是属于每个类实例的变量,用于保持对象的状态。属性可以是基本数据类型、其他对象或任何Python支持的数据类型。 方法(Methods):实例的方法是定义在类中的函数,用于修改实例的状态或执行与实例相关的操作。方法的第一个参数通常是self,它...
This method also has some advanced use cases in Python. One of these use cases is when you want to create class-based decorators. In this situation, the .__call__() method is the only way to go because it enables callable instances. Another interesting use case of .__call__() is ...
