Hi Jacob,
Watch out with your code,
###
if i==1000:
i=0
else:
i=i+1
###Since this test is done after you have stored your data you are actually going to store 1001 pieces of data.
i starts at 0
you store 0
you do your test and i is incremented
{that's set 1}
i is 1
you store 1
you do your test and i is incremented
{that's set 2}
...
i is 1000
you store 1000
you do your test and i is set to 0
{that's set 10001}
Also, it looks like you have that i-incrementing happening at the same level as the if-test. If so, it is possible that the i's that are used to store the data will not increase by 1 each time since they are being incremented for every k and not only when the data is being stored. If you only want it incremented when something is stored, put it inside the if-block. Also, consider using the modulo operator to keep track of i: replace your test with
### i = (i+1)%1000 ###
i starts and 0 and will be incremented until it is 999 and then when this calculation is then performed you will calculate (999+1)%1000 which is 1000%1000 which is 0--just what you wanted. Here's an example that cycles through 3 number, 0, 1, and 2:
### >>> j=0 >>> for i in range(10): .. print j .. j = (j+1)%3 .. 0 1 2 0 1 2 0 1 2 0 ###
