Python Object-Oriented Python Instant Objects Your first method

Why am I getting this error message?

When I run this code I get the error message

"Oh no! You forgot the self argument in your praise method"

But as far as I can tell I have included the 'self' argument in the parenthesis in the method. I don't understand what I am doing wrong?

Any ideas?

Thanks.

first_class.py 
class Student:

    def praise (self):
        name = "Pete"
        print("Great job{}!".format(name))

me = Student()
me.praise()

For two reasons:

1) At the beginning of the challenge, there is a code-stub where name is given as a class attribute/property. You should leave it be. At the moment you have moved it inside your method, making it a local variable.

2) Your method should return a message. At the moment it doesn't return, it prints it instead.

Remember that you call a class attribute via self.attributename

The challenge asks that "*The method should return a positive message, it won't need to "print" anything.

And the "self" prefix should be used when referencing the instance attribute "name". And that attribute should be defined at the class level, outside of the method (as provided in the original code).

Thanks both for your replies -. I realised my mistake soon after posting this question. Should have used self.name rather than move the attribute called name.
