The key here is that you only want to round for printing. So the best
solution is a format string:

print "%5.2f" % stock[2]

will print the number as at least 5 characters, two of which are after
the decimal point.

Thus

7.070006  -> ' 7.07'     # pads to 5 chars, rounding down
1237.89   -> '1237.89'   # prints *at least* 5 chars
12.56921  -> '12.57'     # rounds up

Look at the first page of the Basics section ofmy tutor for more
info on format strings.
