Assignment 2 Question 6.py

#COMPLETED
#TESTED

"""
For IP course, the performance in different elements of the class for students is 
given in a file (IPmarks.txt) - one line per student as comma separated values:

Roll_no,  m1, m2, m3, … 

Roll_no is a string, while m1, m2, … are integer marks the student got in assessment 
1, 2, …

Separately, the weight of each of the assessments is given as a list of tuples 
(you can hard code this in your program - assume that correct number of items is 
provided): 

wts = [(10, 5), (20, 5), (100, 15), (40, 10), …]

Where the first item is the maximum marks of the assessment, and the second is the 
weight in % this assessment carries in the final evaluation (the sum of weights 
should be 100). In the above, assessment 1 (say, a quiz) has maximum marks of 10 
and its weight in the final total is 5%; assessment 3 has max marks of 100, 
and its weight is 15).
 
For each student, compute the weighted sum of marks normalized to 100. 
(For weighted sum, assessment 1 marks can be normalized to 5, assessment 3 to 15, …), 
and the grade, and write it in a file (IPgrades.txt)  as: 

Roll_no, total_marks, grade

For grading, assume that A is above 80%, A- from 70, B from 60, B- from 50, C from 40, 
C- from 35, D from 30, and below 30 is F.
