How do you pass in parameters?  Consider:

    def square(x):
        return x*x


    def square(x)
        while True:
            yield x*x

How do you get another value of x into the generator?

    >>> def square(x):
    ...   while True:
    ...     yield x*x
    >>> g = square(2)
    >>> g
    <generator object at 0x3b9d28>
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: expected 0 arguments, got 1
