Exception: argument of type 'NoneType' is not iterable

Seems to not work in the Workspace and I can't figure out what the issue is

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()

        else:
            self.reassurance()

:warning: Be careful about testing a challenge in an external REPL. When you work externally you may not be testing for purpose with the same stringency that the challenge does.

In this case, when the grade is 50 or below, the method needs to "return the reassurance method's result". The code shown here just calls the method without returning the result.
