Calculating the average This part is done in (calculating_average. py) In this part, you will read your previously created "records.txt" file and calculate the weighted average for each student. In the previous records example, the average for each student will be: 93x3 + 75.5x3 + 80×2 Nina: = 83.18 3+3+2 90x2 Sarah: 2 = 90 Converting average to letter grade This part is done in (calculating_average.py) In this section, you will map the number grades to letter grades based on the ranges in this link. In our example, Nina's grade (83.18) will be mapped to "A" and Sarah's grade (90) will be mapped to "A+". Creating the average records This part is done in (calculating_average.py) For the last part, you will have to store the average records in a new file called "gpa.txt". This file includes the student's name and total letter grade. The "gpa.txt" file for our example will look like this: Nina A Sarah A+
