1,450 PointsThank you! Could I ask why that's necessary when my variable is in fact "name"? Since I'm just replacing a placeholder, why is the "self" part necessary? Thank you so much!

Treehouse Moderator 68,423 PointsThis is a more advanced question. If you don’t understand the following, come back after classes have been covered in more detail.
When working with an instance of a class, the self points to the instance under consideration. To access the name attribute of this instance, the "dot" notation is used: self.name.
By using just "self" the format would try use the instance of Student. This fails because Student doesn't have a __str__ method to return a value when an instance of Student is used in a string context such as this formatting case.
There is a way just "self" would work, but you might not understand it until you cover magic methods. The following code would work if a __str__ method is added:
class Student:
name = "Manuja"
def praise(self):
return "Well Done %s"%self
def __str__(self):
return self.name
In the above code, self is used in a text context, which cause a call to the instance __str__ method, which returns self.name. This value can successfully be used in the string format!

Treehouse Moderator 68,423 PointsIf one just wants the answer without an understanding of why, a cut-and-paste solution will always seem better. 👍

class Student:
/n
name = "Your Name"
/n
def praise(self):
/n
return "Well done {}!".format(self.name)

Logan Eppley
Courses Plus Student 26,697 Pointsclass Student:
name = "Your Name"
def __init__(self, name):
self.name = name
return("You are doing great, {}".format(name))
Would this not accomplish the same thing?
Chris Freeman
Treehouse Moderator 68,423 PointsThe __init__ should not return a value. Running your code produces:
>>> s = Student("bob")
Traceback (most recent call last):
File "<string>", line 7, in <module>
TypeError: __init__() should return None, not 'str'
And the praise method would still need to reference self.name

Anyone see the problem here?

1,450 PointsWhoops sorry, the question is - """ This class should look familiar! I need you to add a method name praise. The method should return a positive message about the student which includes the name attribute. As an example, it could say "You're doing a great job, Jacinta!" or "I really like your hair today, Michael!". Feel free to change the name attribute to your own name, too! """
