Introduction

Set the grades according to the points given to the exercises.

Theory

Save the database as a csv file and read it. Choose the exercises and run the python script.

#Python3

import math
import glob
import numpy as np

    ti = []
    for title in titles[1:]:

    r = [row[0]]

    points = []
    for i,p in enumerate( row[1:] ):
        #Convert the numbers separated by space into a array of integers
        #Fetch the max value of and return those.
        #print( p )
        #print( [(i) for i in p.strip().split(' ')] )
        values = [int('0'+i) for i in p.strip().split(' ')]
        #print( values );
