From your home directory go to your it116 directory 
cd it116
Go to your hwdirectory 
cd hw
Create an hw4 directory 
mkdir hw4
Enter this new directory 
cd hw4

Specification

This program should prompt the user for a score, convert it into an integer and print the letter grade for that score in this course.

You will find the ranges for each of the letter grades here.

You should use a single if statement for this assignment.

Your if statement should not print anything, but should set a variable that is used in a final print statement at the end of the program.

Suggestions

Write this script in stages, testing your script at each step
  1. Copy the script grade4.py from Class Notes 7 into the file hw4.py.
    Test this file several times giving it different grade values.
    Fix any errors you find.
  2. Add code for A-.
    Test the code and fix any errors.
  3. Add code for B+ and B-.
    Test the code and fix any errors.
  4. Add code for C+ and C-.
    Test the code and fix any errors.
  5. Add code for D+ and D-.
    Test the code and fix any errors.

Be sure to test your script for all the values you see above since I will use all of them in testing your script.

Be sure to run this script on the Unix machine so you know it works in the environment in which I will run it when I score your homework.
