Stuck on a Class (self) related code challenge. I think I have the correct code?

Hi, so right now I'm learning about Python classes, which is quite cool actually. I've been enjoying it a lot! I just recently got to this coding challenge that wants me to take the 'class Student' (which has a 'name' attribute) and define a praise method, which all it tells me to do is return a nice positive message using the 'name' attribute. It also wants me to use an instance of the class.

So down below is my code, in my 'praise' method I used the 'self' argument (which it also wants me to do), and I have it return a print message, which then calls 'Student.name'.

Whenever I run this code through the code challenge, it just gives me a "Oh no! You forgot the self argument in your praise method". However I'm not sure where I'm forgetting one, I have it in my arguments and it seems to work fine. Do I need to add another one?

When I run the code in my workspace, it seems to print out the desired result. The short praise message with the name included. So I'm a little confused on what's going on, sorry if I'm missing something obvious hehe. Thank you!

first_class.py
class Student:
    name = "TestName"

    def praise(self):
        return print("You're doing great {}!".format(Student.name))
#end    

me = Student()

me.praise()

You have two mistakes. The first one is that your praise should return a string, and not the return value of the print method. In other words, you don't need the print method; The second thing is that to access an instance's attribute you should call it using self with self.attribute
