Nathan's FizzBuzz thingy

nathanfizzbuzz.py

x = 1
for x in range(1,101):
    y = x%3
    z = x%5
    if y + z == 0:
        print 'FizzBuzz'
    else:
        if y == 0:
           print 'Fizz'
        else:
           if z == 0:
              print 'Buzz'
           else:
              print x

There's quite a bit happening in that one line. I split it up into a much longer version with heavy comments explaining how it works:
