Help with my code!

Alright, I need you make a new method named feedback. It should take an argument named grade. Methods take arguments just like functions do. 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.

first_class.py 
class Student:
    name = "Your Name"
    grade = 0

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

Pretty close-- but you need some minor fixes.

  1. On the feedback, you need self as the first parameter rather than grade.

  2. When you test the grade, you should not be referencing "self.grade" but just the "grade" parameter

  3. When a class calls/executes its own function, you need to add self. See below:

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:
            # call the self.praise method
            return self.praise()
        else:
            # calling reassurance method
            return self.reassurance()

You have the right idea, but a few implementation issues:

  • the "self" parameter should be the first thing in the parameter list
  • since "grade" is a parameter, it won't need a "self." prefix
  • but the methods you are calling will need a "self." prefix
  • neither method takes an argument

CAn`t we assign after name as variable such as grade=random(1,100) ?

Assigning a grade isn't part of this challenge, only using one that has already been set to create a response.

What is wrong with this code ?Can't I define grade after name with random function?

import random class Student:

name = "Your Name"
grade=random(1,100)
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:
        # call the self.praise method
        return self.praise()
    else:
        # calling reassurance method
        return self.reassurance()

That's not what the challenge is asking you to do.
