def __init__(self, x=0, y=0, flights_completed=0): Rocket.__init__(self, x, y) self.flights_completed = flights_completed 这样写看起来可读性更高,但是我们更倾向于用 super() 的语法。当你使用 super() 的时候,不必关心父类的名字,以后有改变时会变得更加灵活。而且随着继承的学习,以后可能...

Inheritance in Python is a mechanism that allows one class (the subclass or derived class) to inherit attributes and methods from another class (the superclass or base class). This facilitates code reuse and the creation of a hierarchy of related classes. class Animal: def __init__(self, ...

使用super() 函数:super() 函数用于调用父类(超类)的一个方法。在多重继承中,super() 可以帮助你按照MRO的顺序调用父类的方法。例如: python class D(B, C): def show(self): super().show() # 调用MRO中的下一个父类的方法 通过这些方法,你可以在多重继承中有效地解决冲突或不明确的情况。
