Exception: __init__() missing 1 required positional argument: 'grade'

I think I am doing everything correctly but somehow it says I am still missing positional argument "grade" ..

first_class.py 
class Student():
    def __init__(self, name, grade):
        self.name = "Sabine"
        self.grade = int

    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, grade):
        return "your grade is {}".format.randint(self.grade)
        if grade > 50:
            return self.praise(),
        else:
            return self.reassurance()

In a sense, it's the challenge that's missing something. You added "grade" as a required argument for creating the "Student" class. But this was not part of the instructions, and when the challenge tests the code, it's not supplying that argument.

The only required argument should be "name". Then in task 2 you add code to handle optional arguments.
