I have recently been listening to a few of the NDC talks from around the world and the one today that has caught my interest is this one, Clean Coders Hate What Happens to Your Code When You Use These Enterprise Programming Tricks by Kevlin Henney.

I particularly liked the inclusion of FizzBuzz Enterprise Edition. For those that don’t know FizzBuzz is a simple programming challenge, that used to be and still is in some organisations an interview question.

The problem is

For numbers 1 through 100,

if the number is divisible by 3 print Fizz;
if the number is divisible by 5 print Buzz;
if the number is divisible by 3 and 5 (15) print FizzBuzz;
else, print the number.

It is not a difficult problem, and it can be solved in a few simple lines of code.


def fizzbuzz(n):
if n % 15 == 0:
return 'FizzBuzz'
elif n % 3 == 0:
return 'Fizz'
elif n % 5 == 0:
return 'Buzz'
else:
return str(n)


there are even more concise versions of this code but this is simple to read and understand.

What FizzBuzz Enterprise Edition does is humorously take certain enterprise software design principles to their extreme.
