# basic approach:

if i%3 == 0 and i%5 == 0:

print "FizzBuzz"

elif i%3 == 0:

elif i%5 == 0:

Why evaluate i%3 and i%5 twice?

"""

if i%3 == 0:

msg += "Fizz"

if i%5 == 0:

msg += "Buzz"

if msg:

print msg

else:

print i

def fizzbuzz3(n):

"""

use conditional expressions:

"""

for i in range(1, n+1):

msg = "Fizz" if i%3 == 0 else ''

msg += "Buzz" if i%5 == 0 else ''

print msg or i

the one liner

"""

for i in range(1,n+1): print ( "Fizz" * (not (i%3)) + "Buzz" * (not (i%5)) ) or i

This is a one-liner version inspired by the Ruby one-liner

found here:

This uses list comprehensions, and slicing, and is, well, pretty darn ugly!
