__init__ question

The question states: Our Student class is coming along nicely! 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.

I'm stuck on how to do this. I tried googling how to override the init method and the sample code below was something close to what other people were saying in stackoverflow but obviously this is not correct.

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

    def __init__(self, name=None, **kwargs):
        super(Student,self).__init__()
        self["name"]=name
        for key, value in kwargs.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()

you remove the super class its not necessary and after that line its self.name = name put the colon : after the items(): then you will get it write

Hi! I think you are overthinking it!

The first challenge, you just have to do self.name = name, so when the class is instanced, name is going to be a requirement: 

class Student:

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

The second one requires to use setattr:

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

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

Okay, so you are pretty close, I have added some comments that I hope will help you understand what is going on: 

""" You don't have to initiate name with a value, the argument alone is enough """
def __init__(self, name=None, **kwargs):
""" super() - calls methods on the parent class, and is not necessary in this challenge."""
        super(Student,self).__init__()
"""this line is fine, although I prefer dot-notation myself. 'self.name'
        self["name"]=name
""" This one is also correct, just remember to put the colon after 'items():'"""
        for key, value in kwargs.items()
            setattr(self,key,value)

Here is my solution : 

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

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

Hope this was helpful.

It's very typical to forget small stuff like that. I would recommend using pycharm, or a text-editor on the side while walking through the tracks here on treehouse. That way you can get used to the error-messages and to find bugs like this in your code
