Playing code golf with Python, this is the shortest I could get: https://gist.github.com/tghw/3702360 Definitely a little unpythonic.
Mine is shorter i believe?

Here's mine:
['Fizz' * (not bool(i % 3)) + 'Buzz' * (not bool(i % 5)) for i in xrange(1,101) if i % 3 == 0 or i % 5==0]
EDIT: I hate lambdas. Also I'm not saying the above is pretty or a good idea, but I had some fun.

#33+1 for the pythonic version
-1 for the weird rest
this assures me that python is the right language for me :)

#34This was what one of our Java coworkers wrote a while back: https://gist.github.com/1337/8155054
I don't think you need to even explicity say he's used to Java.
Wow... I've never felt the need to the use the factory technique.

#35A highly Pythonic, Easier to Ask Forgiveness than Permission[1] version:
FIZZ=3
BUZZ=5
cache = {}
for i in range(FIZZ-1, FIZZ*BUZZ, FIZZ):
cache[i] = 'Fizz'
for i in range(BUZZ-1, FIZZ*BUZZ, BUZZ):
try:
cache[i] += 'Buzz'
except KeyError:
cache[i] = 'Buzz'
for i in range(100):
try:
print cache[i%(FIZZ*BUZZ)]
except KeyError:
print i+1
A generator version:
from itertools import izip, islice
def fizzes():
i=0
while True:
yield '' if i%3 else 'Fizz'
i += 1
def buzzes():
i=0
while True:
yield '' if i%5 else 'Buzz'
i += 1
def numbers():
i=0
while True:
yield str(i+1) if i%3 and i%5 else ''
i += 1
print "\n".join("".join(parts) for parts in islice(izip(fizzes(), buzzes(), numbers()), 100))Re: Unpythonic Python

Shorter and more pythonic, but not one per line:
' '.join(["FizzBuzz" if n%15==0 else "Fizz" if n%3==0 else "Buzz" if n%5==0 else str(n) for n in range(1,101)])

#38Earlier quoted context omitted.
Something annoying about python is that the word "lambda" is so long for what are supposed to be one-off functions. You have f=lambda x,y=1,a='Fizz',b='Buzz': ... But it's actually shorter to say def f(x,y=1,a='Fizz',b='Buzz'): ... I much prefer Haskell's \x -> x Style lambdas.
I generally don't particularly like giving punctuation meaning that, well, isn't punctuating. The bottleneck when writing code is almost never keypresses. I think CoffeeScript gets it probably the most right of languages I've worked with, in that the choice of punctuation makes intuitive sense... "Hey! It's an Arrow. It goes from here to here". FWIW, I don't like the word "lambda" either... Naming things with one let…
So what about the '*' in C or even better the '.' in so many object oriented language.

No, it's readability and that often comes with terseness. Every line break because I have to spell out lambda or every refactoring that removes the function from its original context so I can avoid a line break is bad for readability. In that aspect the '\' in Haskell does great. Also in Haskell anonymous functions are so important that they definitely deserve their own special character to shorten many expressions.
I only see this becoming a problem if it is used in excess, like in C++ and especially in C++11.

#39Earlier quoted context omitted.
The reasoning behind using '\' for lambda in Haskell was because it sort of looks like a lambda character ( λ vs \ ) if you squint hard enough.
That's just horrible. I don't know what more to say about it than that. How did anyone think this would be a good idea on balance?
When you're writing Haskell in emacs (like you should be), you enable haskell-font-lock-symbols in haskell-mode, and it displays the lambda as it should be (plus a bunch of other symbol corrections for ::, ->, =>, (), ||, &&, etc.)

Re: Unpythonic Python
#40When you write too much Haskell, your Python code starts to look like this:
print('\n'.join(
'FizzBuzz' if x%5==0 and x%3==0
else 'Fizz' if x%3==0
else 'Buzz' if x%5==0
else str(x)
for x in range(1, 101)))
