I think I missed a concept here. can someone take me through what is wrong with my code and correct my logic.

I am not sure where I am going wrong with my code logic. May someone provide me with a step to step analysis of the expected solution

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:
            New_Student = Student()
            New_Student.praise(self.name)
        else:
            New_Student = Student()
            New_Student.reassurance(self.name)

Look at the code 👇

class Student:
    name = "Melisa Magweezi"

    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)

If I tell you, use the praise method and the reassurance method, you would first make an instance of the Student class like this

>>> melisa = Student()

Now melisa is an instance of class Student, to use the methods you might go something like this;

>>> melisa.praise()
"You inspire me, Melisa Magweezi"

>>> melisa.reassurance()
"Chin up, Melisa Magweezi You'll get it next time!"

So now, bring the feedback method into picture;

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.praise() = melisa.praise(), same like above examples.
        else:
            return self.reassurance() 👈# self.reassurance() = melisa.reassurance(), same like above examples.

You have to call them by using the instance, not the class

Something you still don't get, tag me again, here.

Noted thank you. Self in this case there for refers to the current instance of the class? There is no need to create a new instance?

self can be any instance, new or old, 1 instance or an infinite amount of instances.

>>> melisa = Student()

>>> oliver = Student()

>>> max = Student()
