Fizz buzz

Fizz buzz is a group word game for children to teach them about division.[1] Players take turns to count incrementally, replacing any number divisible by three with the word "fizz", and any number divisible by five with the word "buzz".


Players generally sit in a circle. The player designated to go first says the number "1", and each player thenceforth counts one number in turn. However, any number divisible by three is replaced by the word fizz and any number divisible by five by the word buzz. Numbers divisible by 15 become fizz buzz. A player who hesitates or makes a mistake is eliminated from the game.

For example, a typical round of fizz buzz would start as follows:

1, 2, Fizz, 4, Buzz, Fizz, 7, 8, Fizz, Buzz, 11, Fizz, 13, 14, Fizz Buzz, 16, 17, Fizz, 19, Buzz, Fizz, 22, 23, Fizz, Buzz, 26, Fizz, 28, 29, Fizz Buzz, 31, 32, Fizz, 34, Buzz, Fizz, ...


Fizz buzz (often spelled FizzBuzz in this context) has been used as an interview screening device for computer programmers.[2][3] Writing a program to output the first 100 FizzBuzz numbers is a trivial problem for any would-be computer programmer, so interviewers can easily filter out those with insufficient programming ability.

Python code

for n in range(1, 101):
    response = ''

    if n%3 == 0:
        response += 'Fizz'
    if n%5 == 0:
        response += 'Buzz'

    print(response or n)
