Need help doing this part of a task. How can it be done?

You task is to write a flask application in python that shows students, courses and grades.

The application uses three files to store data.

Input

The three input files are called grades.tsv, courses.tsv, and students.tsv. These contain data in tab-separated format.

The grades.tsv file has the following format ({} denote variables):

{student_no} {course_code} {grade} 

I.e., each line is a grade of a certain person on a specific course.

• student_no is a numerical value
• course_code has the format XXXYYY where X is a capital letter ([A..Z]) and Y is a digit ([0..9])
• grade is a value in the A..F range

The courses.tsv file contains the names of courses, one line per course:

{course_code} {course_name} 

The students.tsv file contains the names of students, one line per student:

{student_no} {student_name}
