Assignment 2: Drawing with cTurtle

The purpose of this assignment is to practice writing Python programs. You are expected to complete the assignment with one partner. It must be handed in electronically by the start of class on Friday.

Today in class, you and your partner each received a slip of paper bearing the name of animal. You may choose either of these animals for what follows. You and your partner will write a single Python program together, in a file animal.py. The program uses the cTurtle module to produce a single image with these components:

• a picture of the animal
• the animal's name (e.g. "dog", not "Clifford")

Your work will be graded according to the following criteria. Warning: If you are doing your homework on your own computer, then you must make sure that your program works on the lab machines. It will be graded on the lab machines.

• There is a recognizable rendering of the animal (3 points).
• There is a legible rendering of the animal's name (3 points).
• The code is clean and well-commented (3 points).

You might want to go back to Getting Started with Python to review what "well-commented" means. In particular, don't forget to include both authors' names at the top of the program.

Here is how you submit your work electronically on a Mac. Warning: You cannot alter your work, once you've submitted it.

• In the Finder program, select the Go menu, then Connect to Server....
• Type courses.its.carleton.edu/COURSES.
• Enter your username and password; the COURSES file server should open in a new window.
• Navigate to the student work section of our course — that's w10, then cs, then cs111-03-w10, then Student Work.
• Select either your folder or your partner's. The two of you are going to hand in just one copy of your work. Please do not place your work into both students' folders; this confuses the grader.
• Inside your folder (or your partner's), select hand-in.
• Drag your file animal.py into the hand-in folder.
