Answer 1

class test_class():
    def __init__(self, some_func):
        self.some_value = 2    
        setattr(type(self), some_func.__name__, some_func)

def my_requested_func(self):
    print(self.some_value)

class_instance = test_class(my_requested_func)
class_instance.my_requested_func()

这应该可行，但我看不出你有任何理由想要这样做。
