A little doubt in classes

class Student():
    name = 'John Wick'
    def praise(self):
        return ("you look great today {}!!".format(Student.name))

code 2

class Student():
    name = 'John Wick'
    def praise(self):
        return ("you look great today {}!!".format(self.name))

both gives the same output,but what's the different between in using 'self' and class name

The term "self" refers to the specific instance, and "Student" refers to the class itself. They only seem interchangeable when using them with class attributes. Otherwise, they could produce different values or possibly one could cause an error.

It's unlikely that you'd ever really want to reference the class by name from within the class. The "self" reference will be the one you want for most cases.

class.name is referring to the class (i.e. Student) you are writing. You don't have self yet. You have self when you create an instance of class Student. Once you have something like emily = Student(). Then, self is emily (or emily is self).
