Possible to pass a function into a object's method as an argument, which can refer to that object?

Question

def my_func():
    stuff
    return something

my_object.my_method(my_func)

I want my_func to be able to refer to my_object. Essentially like deferred self, which means "whatever object I am in, refer to that"

Answer 1

You could use the inspect module

import inspect

def my_func():
    stuff
    my_object = inspect.stack()[1][0].f_locals["self"]
    return something

However, I guess a simpler approach would be to pass the instance as argument, such as

def my_func():
    stuff
    return something

my_object.my_method(my_func, caller=my_object)

You want to make a callback.

And here is a usage of callback in a design pattern.
