Exercise 7.1: A simple example of variable arguments

Try defining the following function:

>>> def avg(x,*more):
        return float(x+sum(more))/(1+len(more))

>>> avg(10,11)
10.5
>>> avg(3,4,5)
4.0
>>> avg(1,2,3,4,5,6)
3.5
>>>

Notice how the parameter *more collects all of the extra arguments.
