Object-Oriented Method Interactivity

I really can't find the solution. I am not sure I am calling the methods in the right way (in my if condition) but I do not have any clue on how to do it. Please help!

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):
    int self.grade
    if self.grade > 50:
        return praise()
    else:
        return reassurance()
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):
        int grade
        if self.grade > 50:
            return praise()
        else:
            return reassurance()

There are a couple of issues:

  1. The grade variable is meant to be a parameter for the method, that means that you have to define it within the parenthesis of the method declaration, not create it within the method.

  2. Since grade is a parameter and not a field belonging to the object you should not use self to refer to it.

  3. Since praise and reassurance do belong to the object they do have to be referred to using self.

Like this:

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): # Add grade as parameter
        if grade > 50: # Change self.grade to grade
            return self.praise() # Change praise() to self.praise()
        else:
            return self.reassurance() # Change reassurance() to self.reassurance()
