Python 2.7 interpreter, after calculating factorial with the obvious 
loop.  Basically, it's using repr() on the expression, so it flags the 
integer as a long, rather than an int.

I debated not including it, but this way I was sure of getting the right 
number of zeroes.  My copy/paste is notorious for missing a character or 
two at each end.
