[New-bugs-announce] [issue18252] timeit makes code run faster?

[icedream91]

New submission from icedream91:

I used Python 3.3.2 to try this problem: http://projecteuler.net/problem=23 , and I got a correct answer.

When I wanted to check how long it took, I found something strange:
When I ran 23.py directly, it showed that it took about 13s. But if I use timeit module, it showed that it only took about 9s! I have tried these for some times, in both Ubuntu 12.10 and Windows 8, I don't understand why timeit will make the same code run faster.


Thanks.
