There are two typical use cases for super. In a class hierarchy with single inheritance, super can be used to refer to parent classes without naming them explicitly, thus making the code more maintainable. This use closely parallels the use of super in other programming languages. 注意super()...
但当去调用aa这个对象的call_wind属性时,前提是又要去调用__getattribute__方法,反反复复,没完没了,形成了递归调用且没有退出机制,最终程序就挂了! 2.11 __ delattr__() 本函数的作用是删除属性,实现了该函数的类可以用del 命令来删除属性。 class MyClass: def __init__(self work, score): selfwork...
super().__init__(param1, param2) The Python super() method lets you access methods from a parent class from within a child class. base class in python Abstract base classes provide a blueprint for concrete classes. They don't contain implementation. Instead, they provide an interface and...
Note:Following the state ofkwargscan be tricky here, so here’s a table of.__init__()calls in order, showing the class that owns that call, and the contents ofkwargsduring that call: ClassNamed Argumentskwargs RightPyramidbase,slant_height ...

pygame.init(): 这个方法将初始化 pygame 内嵌的一系列模块/类。这意味着我们可以使用 pygame 的命名空间调用其他模块。 pygame.display.set_mode((width, height)): 作为元组(width, height)传递的大小是期望的屏幕大小。这个大小代表我们的游戏控制台。返回的对象将是一个窗口屏幕,或者表面,我们将在其中执行不同...
super().__init__() #也能正确调用父类方法 >>> b = B() B.__init__ A1.__init__ 3. 不带任何参数的super等效于super(类名,self),此种情况多用于单继承关系的子类中。 #super不带参数 >>> class B(A1): def __init__(self): ...
This will create a pages/ directory with several files: __init__.py tells Python to treat the directory as a Python package. admin.py contains settings for the Django admin pages. apps.py contains settings for the application configuration. models.py contains a series of classes that Django’...
