I'd like to be able to set the name attribute at the same time that I create an instance. Can you add the code for doing

How to solve below challenge and please explain me **kwargs and also for key, vlaue stuff in the function I'd like to be able to set the name attribute at the same time that I create an instance. Can you add the code for doing that? Remember, you'll need to override the init method.

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

    def __init__(self):
        name = 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 Sanjay,

You have successfully overridden the init method, but not correctly.

First off, you need to add a name argument to __init__:

def __init__(self, name):

Second, the order of the code inside the method is reversed, it should be -> where_you_want_to_be_stored = what_you_want_stored

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

Now for **kwargs...

**kwargs allows you to pass keyworded variables as arguments to a function. (**kwargs is just a convention, you could write it with anything proceeding two asterisks (**))

For example:

def myFunction(**kwargs):
    for key, value in kwargs.items():
        print(key + " = " + value)


myFunction(name = "Sanjay") #  prints "name = Sanjay"

import random

class Dice(object):

def init(self, *args, **kwargs): self.name = kwargs.get('name', 'no_name') self.sides = [1,2,3,4,5,6]

def roll(self): return random.choice(self.sides)

d = Dice(name='first_dice')

print(d.roll())
