I was surprised by the speed and number of posts.  Thanks for the 
solutions provided!

 >>> def roll(times=1, sides=6):
...     return random.randint(times, times*sides)

Although this would probably be quicker than the other approaches, I'm 
not using the dice to generate numbers per say, I actually want to 
emulate the rolling of dice, bell-curve (normal distribution) as well as 
the range.

Thanks again, I already like what (very) little I can do in Python and 
it seems to have a great community too.
