Use class method polymorphism to provide generic ways to build and connect concrete subclasses. Item 25: Initialize Parent Classes with super Python’s standard method resolution order (MRO) solves the problems of superclass initialization order and diamond inheritance; Always use the super built-in ...

我们可以将该类加载到 Python 3 解释器中,这样我们就可以交互式地使用它。为了做到这一点,将前面提到的类定义保存在一个名为first_class.py的文件中,然后运行python -i first_class.py命令。-i参数告诉 Python运行代码然后转到交互式解释器。以下解释器会话演示了与这个类的基本交互:...

If a variable name is not found in the dictionary of the current class, the parent classes are searched for it. The += operator modifies the mutable object in-place without creating a new object. So changing the attribute of one instance affects the other instances and the class attribute ...
