Argument of type method is not iterable? Can you give me any hints on what I am missing here?

I feel like the code should work. What am I missing? self?

first_class.py 
class Student:
    name = "Your Name"

    def praise(self):
        return "You inspire me, {}".format(self.name)

    def reassurance(self):
        return "Chin up, {}. You'll get it next time!".format(self.name)

    def feedback(self, grade):
        if grade > 50:
            return self.praise
        if grade <= 50:
            return self.reassurance

Because of the way challenges are evaluated, sometimes the relevance of the error message isn't obvious. But as Youssef pointed out, whenever you call a method you must put a pair of parentheses after the method name. Otherwise, you are returning a reference to the method itself but the challenge is expecting to see the results of the method.

omg thanks. I definitely forgot they are methods because I'm not used to returning methods within methods. More used to the way of instantiating new objects and calling it from there.
