The Classic Fizz Buzz Problem
==============================

Fizz Buzz is a classic simple problem in computer science.

It is often used as an exercise in interviews for programmers.

Apparently a LOT of people applying for jobs as professional developers can't do this in an interview:

Now that we've psyched you out -- it's really pretty straightforward.

Goal:
-----

* Write a program that prints the numbers from 1 to 100 inclusive.

* But for multiples of three print "Fizz" instead of the number.

* For the multiples of five print "Buzz" instead of the number.

* For numbers which are multiples of both three and five print "FizzBuzz" instead.

Hint:
-----

* Look up the ``%``  operator. What do these do?

  * ``10 % 7``
  * ``14 % 7``

(try that in iPython)

* **Do** try to write a solution *before* looking it up -- there are a million nifty solutions posted on the web, but you'll learn a lot more if you figure it out on your own first.


Results:
--------

Running your code should result in something like::

    1
    2
    Fizz
    4
    Buzz
    Fizz
    7
    8
