动态地对python 2.7类进行修补

想知道是否有人有一个很好的方法来动态地检查一个类的函数类型，然后动态地将一个装饰程序修补到其中一些函数上。我正在尝试，但没有得到我期望的结果。在课堂上遍历这些方法似乎是可行的，但猴子补丁本身似乎失败了。任何想法都非常感谢

def decorator(callable):
    pass

class Test(object):
    def foo1(self):
        return self.bar()

    def foo2(self):
        return self.blah()

    def foo3(self):
        return 0

for x,y in Test.__dict__.items():
        if type(y) == FunctionType:
            Test.x = decorator(Test.x)

---

当然，

Test.x

不存在，这将引发

AttributeError

。您可以为此使用

setattr

。同样

x.\uu dict\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

for x,y in vars(Test).items():
    if type(y) == FunctionType:
        setattr(Test, x, decorator(y))

当然，
Test.x
不存在，这将引发

x.\uu dict\uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

for x,y in vars(Test).items():
    if type(y) == FunctionType:
        setattr(Test, x, decorator(y))

这种动态添加装饰器的方法是完全有效的。我也希望Python提供更好的语法，但目前还可以，这种动态添加装饰器的方法是完全有效的。我还希望Python提供更好的语法，但目前还可以。
