\r\n

Unfortunately, a more careful inspection of the problem specification reveals this solution was incorrect.

\r\n

Write a program that prints the numbers from 1 to 100. But for multiples of three print “Fizz” instead of the number and for the multiples of five print “Buzz”. For numbers which are multiples of both three and five print “FizzBuzz”.

\r\n

Luckily, that’s a very simple fix:

# codegolf version (90 characters):\r\n[{0:"fizzbuzz"}.get(x%(3*5),{0:"fizz"}.get(x%3,{0:"buzz"}.get(x%5,x)))for x in range(101)]\r\n \r\n# slightly more readable:\r\n[{0: "fizzbuzz"}.get(x%(3*5), \r\n                     {0: "fizz"}.get(x%3, \r\n                                     {0: "buzz"}.get(x%5, x))) \r\n for x in range(101)]

There you have it, a solution to the fizzbuzz problem that relies on \r\npython’s interactive command line interpreter thingy to do the printing,\r\nshaving off 4 characters for print.

\r\n

The “trick”, if it can be called that, is relying on the native get method\r\n to return the correct string or fall back to the default value, which \r\nchecks for the next string in the if-then-else chain.

\r\n

I wish never to see code like that in something I have to maintain. Ever.

\r\n

The challenge

\r\n

Your challenge, should you choose to accept it, is to produce a \r\nshorter fizzbuzz solution without using if sentences. I will buy a \r\nbottle of beer for the winner.

\r\n

The best Scala solution so far is 106 characters, by @HairyFotr:

1 to 100 map(a=>println((a%3,a%5)match{case(0,0)=>"fizzbuzz"case(0,_)=>"fizz"case(_,0)=>"buzz"case _=>a})) /cc

No really, I will send a bottle of beer anywhere in the world if you write a shorter solution. Of course, if feasible, I would prefer to take you out for a beer than use snail mail \":)\"

Yesterday I got nerd-sniped into solving the FizzBuzz problem without using if sentences.

\r\n
\r\n

Fizzbuzz, no ifs: [{0: "fizzbuzz"}.get(x%(3*5), {0: "fizz"}.get(x%3, {0: "buzz"}.get(x%5))) for x in range(3, 100, 3)+range(5, 105, 5)]
