Looks like the {{pass}} immediately above closes the if/elif block, which
means the two lines of code dealing with average and average2 only get
executed in the "elif perc >= 45" block. That means average2 wouldn't even
be defined otherwise, so I would expect you would be getting errors later
in the code whenever there isn't at least one D in the list of grades.
Also, there is no reason to calculate average2 inside the for loop -- you
only need to calculate it once after looping over all the records.
Finall, why not name the variables something like "total" and "average"
instead of "average" (which is not really an average) and "average2"?
