No attribute being found if nothing entered when initiating a class

Hi guys,

I have the following code:

class Student:
    def __init__ (self, **kwargs):
        self.name = kwargs.get('name', 'Dave')
        self.age = kwargs.get('age', 18)
        self.lesson = kwargs.get('lesson', 'NONE')


    def register (self):
        print ("Hi {}".format(self.name))
        print ("\nYou are {} years old and studying {}".format(self.age, self.lesson))

when I run:

bob=Student

Then run:

bob.name

I get the following attribute error:

AttributeError: type object 'Student' has no attribute 'name'

However, if I create an instance of Student and explicitly put in a name value all is fine. It seems to be an issue with the defaults in the get method on kwargs.
