Method Interactivity Stuck on challenge

I am trying to figure out this challenge. But I keep getting an error Exception: reassurance is not defined...

any thoughts?

here is my code

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:
            return(praise())
        if grade > 50:
            return reassurance

You forgot to prefix the method names with "self.".

When calling methods inside your own class, be sure to put "self." in front of the method names.

Also, the instructions say "return the reassurance method's result", but on the last line you return the method itself. To return the method's result, you would call it by placing parentheses after the name like you did for "praise".

Finally, check your conditionals. You might need to make some changes to make sure the right thing happens for the right argument values.

I have no clue what your talking about. I tried the following code, which is correct, and I get the error code... Bummer! Exception: name 'praise' is not defined

class Student: name = "James"

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 praise(self)
    if grade < 50:
        return reassurance(self)

Please advise

The "self." goes in front of the method name, for example:

        return self.praise()

ok. I guess I am missing some critical understanding of the code. Anything you can do to help me to comprehend what I don't understand?

If you mean "why do you add 'self'?", it identifies that a class method is being called instead of a global function of that name. This is similar to the other methods referring to "self.name" instead of just "name".

If that's not what you were asking, perhaps you could be a bit more specific.
