Nothing is executed 8000 times.  I figure it at 3998 times.  Anyway,
neither the for nor the range is executed multiple times.  Deciphering
this depends on whether this is Python 2.x or Python 3.x.

If Python 2.x, range returns a list of 3998 items, and that is iterated
over.
If Python 3.x, range returns a range object, which has an __iter__()
special method.  That method gets called 3999 times, and the last time
it throws an exception to end the loop.
