I have a hunch you're mistakenly thinking that Python is only running
through ten iterations of your for i in range(1000000) loop. This is
not the case. The entire thing is running (all 1000000 iterations of
your loop), but is run ten times, as that is the default for timeit
unless you specify that you want to run it more times. Hope this helps.
Basically timeit is doing something like this:
for i in range(1000000):
for x in range(10):
And then collecting timing statistics on the ten passes.
