Code Challenge: __init__

Hi team!

I'd like to be able to set the name attribute at the same time that I create an instance. Remember, will need to override the init method. Please assist

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

    def __init__(self, name):
        self.name = name
            setattr(self, 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()

Hi mate, so I'll try to help you with both parts of the challenge to the best of my abilities.

PLEASE CORRECT ME IF I GET ANYTHING WRONG

So for the first one, it's pretty simple. it wants you to initialize an attribute. 

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

I got stuck on the 2nd one too but, I managed to pass it. So it wants you to use ** kwargs and setattr to add attributes for any other key/value pairs you........ etc. 

def __init__(self, name, **kwargs):
    self.name = name
    for values, keys in kwargs.items():
        setattr(self, values, keys)

The word "self" is used to represent the instance of a class. it's pretty self-explanatory. to be honest. check this link out if you want to learn more about setattr.

that'll do:

class Student:
    name = "Your Name"


    def __init__(self, name= "Kudakwashe", **kwarg):
        self.name = name

        for key, value in kwarg.items():
            setattr(self, key, value)

    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()
