如何获取实例给出的实例的方法？

问题描述

class MyClass:
    def myMethod(self):
        pass

myInstance = MyClass()

methodReference = myInstance.myMethod

现在可以引用 myInstance 如果你现在只能访问 methodReference ？

Now can you get a reference to myInstance if you now only have access to methodReference?

推荐答案

methodReference.im_self

methodReference.im_class

对于这种代码发现，你应该安装iPython并使用tab，例如，在你的case myReference。+ TAB会给：

For this kind of code discovery you should install iPython and use tab, for instance, in your case myReference.+TAB would give:

In [6]: methodReference. methodReference.im_class 
methodReference.im_func   methodReference.im_self

因此，您不需要担心记住事情这么多 - 你知道该方法可能由函数对象提供，并从建议，iPython给它通常很明显你正在寻找什么方法/属性。

Hence, you don't need to worry about remembering things so much - you know that the method is probably provided by the function object and from the suggestions that iPython gives it's usually obvious what method/attribute you're looking for.
