please help me

I tried and searched in the video, but nothing like this has seemed to be covered

what does setattr do and how do I use it?

first_class.py 
class Student:
    name = "Your Name"

    def __init__(self, name, **kwargs):
        self.name = name


    def praise(self):
        return "You inspire me, {}".format(self.name)

    def reassurance(self):
        return "Chin up, {}. You'll get it next time!".format(self.name)

    def feedback(self, grade):
        if grade > 50:
            return self.praise()
        return self.reassurance()

  1. setattr() will set attributes from a dictionary passed to the init method from **kwargs (key word arguments).

So, if you initialize a Student object after adding this setattr functionality :

tej = Student(name ="Tej", age = "20", country = "Canada")

you should be able to access tej.country even though you didn't specify it in the class declaration.

  1. To use it, iterate through kwargs and call setattr(self, key, value) on each item.
