I'm having a kind of hard time figuring out what's going on here. I'm
guessing that x in range() is just to run the function a number of times
in order to calculate relative time? If so, you might want to output
the time.strftime() with whatever time format you prefer before and
after the execution of the function code, to better time it.
Also, in test1(), you're throwing away z.
Finally, what's dol()? Obviously, since it's a different function than
enumerate(), it might have a different overhead.
