python - 将代码 append 到继承的类方法

Question

您将如何 append 到继承对象的方法？比如说:

class ABeautifulClass(GoodClass):
    def __init__(self, **kw):
        # some code that will override inherited code
    def aNewMethod(self):
        # do something

现在我已经从 GoodClass 继承了代码，我该如何将代码 append 到继承的方法。如果我从 GoodClass 继承代码，我将如何 append 到它，而不是基本上删除它并重写它。这在 Python 中可行吗？

Answer 1

尝试使用 super

class ABeautifulClass(GoodClass):
    def __init__(self, **kw):
        # some code that will override inherited code
    def aNewMethod(self):
        ret_val = super().aNewMethod() #The return value of the inherited method, you can remove it if the method returns None
        # do something
