I don't know how to add an attribute to a method, can someone please help?

In challenge 1 in OOP, I try

class Student:
    name = "Hai"
    def praise(self):
        self = name    #This is where I don't know what to do
        return print("Good job, {}".format(self))

Now I got stuck and I don't have any idea about things interact inside Class!

You don't need to add a new attribute, what you need is already stored in the class as "self.name".

And you only need to return the string directly, you do not need to "print" anything.

I did it but the name attribute didn't store

class Student:
    name = "Hai"
    def praise(self):
        self.name
        return "Good job {}".format(self)

It's already stored, you just need to reference it:

#       self.name                               # this isn't needed (and doesn't do anything)
        return "Good job {}".format(self.name)  # reference the stored name

Yea Hai, you can even do 

return "Good job {}".format(Student.name)

To get the same output I noticed fooling around in my IDE, but it won't pass the challenge unless you use self.name.

You should always reference a non-static property using the instance name, not the class name.
