I can't add the new method 'feedback'

I am doing this class method creation excercise but for some reason it does not work ..

first_class.py 
class Student():
    name = "Sabine"
    grade = grade

    def praise(self, name):
        return "You inspire me, {}".format(self.name)

    def reassurance(self, name):
        return "Chin up, {}. You'll get it next time!".format(self.name)

    def feedback(self, name, grade):
        self.grade = int.input("{}, Your grade is:>  ".format(self.name))

        if self.grade > 50:
            return Student.praise
        else:
            return Student.reasurance

class Student(): name = "Sabine"

grade = grade You will not need this line

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)

You do not need to add "name" to the method arguments.

def feedback(self, grade):

self.grade = int.input("{}, Your grade is:> ".format(self.name)) You will not need this line either, I also took the name argument out.

I switch out self.grade with grade and took the else statement out. Make sure your indentions are correct when doing the code challenge over.

    if grade > 50:
        return self.praise()

    return self.reassurance()

At last I switched student with self and put call signs at the end of each method. Also you misspelled reassurance I hope this helps!

Just wondering ... where did you hear/read/see the term "call signs"?

I associate that term with radio communications, as described in Wikipedia.

The parentheses indicate that you want to call the method. 'praise()' returns the value of the method applied to the argument. If you simply say 'praise', then it returns a method, not the value you get when the method is applied. That is why I call them call signs. It may not be correct terms, but it is my way of putting it in my own words.

Cool, I'll try to remember that next time I use the phase in an open forum
