first_class: "Bummer! Exception: feedback() takes 1 positional argument but 2 were given"

Need help on interpreting how to fix my challenge issue. I am not sure how I am giving two positional arguments in my code

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):
        if grade > 50:
             praise()
        else:
             reassurance()

Hi Cb123,

The error message is not very clear, but when it's talking about the number of positional arguments supplied (2), it is not referring to you calling a function with two positional arguments, but rather the behind-the-scenes code being run by Treehouse when it calls your function to test your code is supplying two arguments.

If we look again at the question text for the challenge we can see a clue to the solution:
"Alright, I need you make a new method named feedback. It should take an argument named grade."

The task is telling you to create a method that has two parameters: self and grade. When Treehouse calls your method it is providing a value for grade and because you haven't implemented grade it's causing the error message about you not having enough positional arguments in your method.

You should find that when you fix this you no longer get the error message you've described. However, you are still going to get a couple of other error messages. Look closely at the specification you were provided for clues on how to fix the remaining errors:

"You'll still need self in there, though. If grade is above 50, return the result of the praise method. If it's 50 or below, return the reassurance method's result."

Hopefully this helps, let me know if you are still stuck.

Cheers

Alex
