Deliverables

There is one deliverable for this assignment

hw8.py

Make sure the script obeys all the rules in the Script Requirements page.

get_artist
print_lp

get_title

This method returns the value of the title attribute.

Script for this assignment

Open an a text editor and create the file hw8.py.

You can use the editor built into IDLE or a program like Sublime.

Test Code

Your hw8.py file must contain the following test code at the bottom of the file:

lp = LP("The London Concert", "Sony Classical", "Wynton Marsalis")
print(lp.get_title())
print(lp.get_label())
print(lp.get_artist())
lp.print_lp()

Run the script.

You should see

$ ./hw8.py
The London Concert
Sony Classical
Wynton Marsalis

Suggestions

Write this program in a step-by-step fashion using the technique of incremental development.

In other words, write a bit of code, test it, make whatever changes you need to get it working, and go on to the next step.

Create the file hw8.py.
Write the class header for LP.
Write the constructor for this class.
Make sure the constructor has parameters for each attribute.
Make sure the constructor sets the value foe each attribute.
Add the first line of the test code to the bottom of the file.
Run the script.
Fix any errors you find.
Create the method get_title.
Add the second line of the test code to the bottom of the file.
Run the script.
Fix any errors you find.
Create the method get_label.
Add the third line of the test code to the bottom of the file.
Run the script.
Fix any errors you find.
Create the method get_artist.
Add the fourth line of the test code to the bottom of the file.
Run the script.
Fix any errors you find.
Create the method print_lp.
Add the last line of the test code to the bottom of the file.
Run the script.
Fix any errors you find.

Testing on Your Machine

Open IDLE
Use the Open command in IDLE to open hw8.py
Under the Run menu, select Run Module
Your output should look something like this

Unix Setup

Log in to users3.cs.umb.edu
You will be in your home directory.
Go to your it117 directory
```
cd it117
```
Go to your hw directory
```
cd hw
```
Create a directory for this exercise
```
mkdir  hw8
```
Check that the directory was created
```
ls
```

Copy the file to Unix

Open FileZilla and connect to users3.cs.umb.edu
You will have to connect using your Unix username and password.
Copy the file to the to it117/hw/hw8

Testing the script on Unix

Connect to
Use an ssh client.
Go to the directory for this exercise
```
cd  it117/hw/hw8
```
Make this script executable
```
chmod  755 hw8.py
```
Run this script
```
./hw8.py
```

You should see

The London Concert
Sony Classical
Wynton Marsalis
The London Concert, Sony Classical, Wynton Marsalis

If your script does not run on users3 you will lose points
