What You Need to Do

• Create the script hw4.py
• Make sure it obeys the rules in Rules for Homework Scripts
• Move it to an an hw4 directory on pe15.cs.umb.edu

Setup On Your Machine

• Open a text editor.
  I would suggest the text editor built into the program IDLE.
• Save the file as hw4.py

Specification

• This program should prompt the user for a score
• Convert it into an integer
• And print the letter grade for that score
• You will find the ranges for each of the letter grades here
• You must use a single if-elif-else statement in this script
• If you use mutliple if statements you will lose points

Output

• The output should look something like this

  Score? 86
  B+

• The text in blue is what the user enters

Suggestions

• Write this script in stages
• Test your script at each step
• Print the steps below
• And check them off as you finish each one

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-.
   Use the >= operator.
   Test the code and fix any errors.
3. Add code for B+ and B-.
   Use the >= operator.
   Test the code and fix any errors.
4. Add code for C+ and C-.
   Use the >= operator.
   Test the code and fix any errors.
5. Add code for D+ and D-.
   Use the >= operator.
   Test the code and fix any errors.

Testing on Your Machine

• Open IDLE
• Use the Open command in IDLE to open hw4.py
• Run your script inside IDLE
• Your output should look something like this

  Score? 86
  B+

• The text colored blue is user input
• You should test your script with the following values to make sure your script works for all scores

  100

Copy the Script to Unix

• Open FileZilla and connect to pe15.cs.umb.edu
• Go to your it116 directory
• Go to your hw directory
• Right-click in the whitespace inside the hw directory
• Enter hw4 in the dialog box
• Click and drag your script from the bottom left panel to the bottom right panel

Testing the Script on Unix (Optional)

• Connect to pe15.cs.umb.edu using an ssh client like putty.exe (Windows) or ssh (Mac)
• Go to the directory for this exercise

  cd  it116/hw/hw4

• Run this script

  python3 hw4.py

• You should see something like this

  Score? 86
