To add a curve to the amount of grades being printed.

Question

Code in python. Given the following list of student test scores, apply a class "curve" to each score. The class curve is as follows:

 

90 or above: no curve

80 to 90: +2 points

70 to 80: +5 points

Lower than 70: +8 points

 

Use the below test scores list:

grades = [93, 74, 66, 98, 34, 75, 79, 83, 84, 91, 12, 69, 72]

Answer 1

The simplest way would be to hardcode the curves:

def curve(grades):

for i, gr in enumerate(grades):

if gr < 70:

grades[i] = gr+8

elif gr < 80:

grades[i] = gr+5

elif gr < 90:

grades[i] = gr+2

return grades

Note that because we start from 70 and use elif, we do not need to specify both the upper and the lower bound of the curve scores. We use the enumerate function to make it easy to modify the list in-place, replacing the old score with the curved score.
