@konstantinfarrell has a gist that’s only 72 characters for anyone arriving to this page from google:
for i in range(1, 101): print('Fizz'*(i%3==0)+'Buzz'*(i%5==0) or str(i))
@andreis line should work with both python 2 and 3 by changing xrange() to range()
Here’s a nice little piece on the range() function.
