Hi Mohamed,

Yeah, your code does work! But you've put the name attribute inside of the praise method. And they want that attribute to be part of the class, not part of the method.

So you can fix that by writing your method below it, and use self.name inside to point it to the right attribute of the class.

Hopefully this makes sense!

class Student:
    name = "Your Name"

    def praise(self):
        return "Great job, " + self.name

I tried

class Student: def praise(self):

    name = "Anser"
    return "I really like your hair today, "+name+"!"

student1 = Student() print(student1.praise())

but my answer was wrong,when I replaced my student class with your's I got it right,how it is ? what is the issue with my code?

There is not really an issue with your code, the method does work!

But since this is a Student class you probably want all your attributes (in this case name) to be part of the class itself. This way you can use your attributes in all the methods you create for this class.

See, I can still access the name attribute in my code:

class Student:
    name = "Harry"

    def praise(self):
        return "Great job, " + self.name

student1 = Student()
print(student1.name)
# gives me back 'Harry'

But in your code, you can't access or reuse it because you made it part of your method.

class Student:
    def praise(self):
        name = "Anser"
        return "I really like your hair today, "+ name +"!"

student2 = Student()
print(student2.name)
# This gives: AttributeError: 'Student' object has no attribute 'name'
