Exception: praise() takes 1 positional argument but 2 were given

What am i doing wrong here?

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(self.name)
        else:
            return self.reassurance(self.name)

For class methods, you don't need to pass the self to the other methods, it's set implicitly by the run-time:

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:
            return self.reassurance()
