The second use case is to support cooperative multiple inheritance in a dynamic execution environment. This use case is unique to Python and is not found in statically compiled languages or languages that only support single inheritance. This makes it possible to implement “diamond diagrams” where...
super()函数来对父类的初始化,在子类中显示的指定父类,调用父类的__init__()来初始化,我们看例子,现在我们有父类P,子类M,代码如下:classP: def __init__(self, name, age): self.name = name self.age = age def getname(self): return self.name def ge
