我试图为类中的每个函数创建一个方法，每次调用函数时都会调用该方法。这个类是另一个类的子类（在我的特定例子中，它是list的子类）。

class Foo(another_class):
    def __init__(self, bar):
        self.bar = bar
        super().__init__(self.bar)

    def function_to_be_called(self):
        self.bar += 1

    def function(self):
        # do stuff

foo = Foo(0)
foo.function()
foo.inherited_function()
print(foo.bar)  # should be 2, since function and inherited_function were called

我发现an answer建议覆盖__getattribute__魔术方法，但这样做会导致无限递归（因为调用的函数需要首先使用__getattribute__找到），或者产生非常奇怪的行为。
我的第一次尝试（导致RecursionError）：

class Foo(another_class):
    def __init__(self, bar):
        self.bar = bar
        super().__init__(self.bar)

    def function_to_be_called(self):
        self.bar += 1

    def function(self):
        # do stuff

    def __getattribute__(self, attr):
        method = another_class.__getattribute__(self, attr)
        self.function_to_be_called()  # this required __getattribute__ to be called to find function_to_be_called, causing an infinite loop
        # even if self.function_to_be_called() is replaced with the self.bar += 1, it still causes an infinite loop as __getattribute__  is called to find bar
        return method

我的第二次尝试还包括答案中的if callable(method)，并将function_to_be_called的内容移动到if语句中，而不是调用函数（p.s.我将酒吧改为列表，因为这是我的初衷，也是我发现奇怪行为的原因）：

# Assume that another_class has an append method
class Foo(another_class):
    def __init__(self, bar):
        self.bar = bar
        super().__init__(self.bar)

    def function(self):
        print(self.bar)

    def __getattribute__(self, attr):
        method = another_class.__getattribute__(self, attr)
        if callable(method):
            self.bar.sort()  # doing something to bar, for example sorting it
        return method

foo = Foo([3, 1, 2])
print(foo)  # [3, 1, 2], although the expected result is [1, 2, 3]. it does not actually seem to be sorting it
foo.append(1)
print(foo)  # [3, 1, 2, 1], although the expected result is [1, 1, 2, 3]
foo.function()  # [1, 2, 3], the other 1 that was appended dissappears randomly (edit: I tried this again, with the actual class that I am using this in, and it seems to work for some reason), and it is sorted for some reason this time
