Exercise $2$: Student Grades

Create a new Python program and save it in your Prac$9$ directory.

You are to write a program which reads a student's Id and exam mark.

It then generates and displays the letter grade for that student.

The program will first ask the user for the student's Id number, and the

mark that they got in the exam. The program should check if the mark

is between $0$ and $100$ inclusive. It should only display a letter grade if

the mark is valid.

The program will need to generate the letter grade based on the table

below:

Display the students Id$,$ original mark, and letter grade. For example:

$10004,100,A$

a$)$ Write the flow$-$chart for getting the student's Id and mark, checking if

the mark is valid and generating a letter grade. Get a demonstrator to

check it before going on to the next step.

b$)$ Now create the program using your flow$-$chart.

c$)$ Test the program with different inputs to make sure the results are what

you expect.
