CSCI1101:Assignment 0

Have a Nice Semester!

Assigned: Tuesday, August 28
Due: Thursday, August 30 at 11PM

The good news: The only deliverables here are under headings 3 and 4 below, and you don't have to do all that much.   The bad news (which is not all that bad): This assignment is due just two days from now.  Starting with Assignment 1,  you will have a week for each problem set.  It is strongly recommended that you complete steps 1 and 2 before the first lab discussion sections on Monday and Tuesday, so you can address any issues that arise.

1. Install the software.

Install Python 3.7.0 from here. Simply click on the link that says Download Python 3.7.0 (more details).

To test if your installation works, navigate to the folder for Python (in the Applications folder on a Mac, or wherever all your programs are listed on Windows) and double-click on the icon marked IDLE. You should see a window open with a message like this

Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24)
[Clang 6.0 (clang-600.0.57)] on darwin
Type "copyright", "credits" or "license()" for more information.

with a blinking cursor after the '>>>'.  Type any number (say, 3) and hit enter.  You should see the number printed on the next line.  Your installation was successful.

If you ran into problems, your TA can help you complete the installation during the first discussion section.

2. Download and run the sample programs

Make a folder called CS1 (or, really, anything else you care to call it), in which you will store all your work for this course.

Download the programs and from the course website and save them in this folder.

Open the file from the File menu in IDLE, and then select Run Module from the Run menu.  You should see the message

Hello, world

appear in the Python Shell window in IDLE.

Now repeat the procedure with the file  Instead of seeing a message in the IDLE window, a rocket ship will appear.  Click on this and you will see the window with the smiley face. Terminate the program by closing this window.

3. Revise the Hello, World program

Remove the comment with my name and replace it with your own.  Now add new statements to print additional lines of text, whatever you like.  You might make a few mistakes along the way--that's fine, that's how you learn--but make sure your program runs before you submit it.

4. Revise the Happy Face program

Similarly, change the comment. Then make a change to one or more of the four drawing instructions; it doesn't matter what you do, as long as you change something and the resulting program runs.  If you're feeling lazy, you don't have to try to understand any of this code: you can do something very simple like change the color of the face  or the eyes. (Python understands quite a large number of color names.) If you're more ambitious, you might want to read the explanation of the drawing commands, modify the size of the face and eyes, put in irises and pupils, change the smile to a frown (not so easy), experiment with the create_rectangle function and see if you can reproduce the picture that illustrates this assignment.

5. What to Hand In

These are the standard instructions for submitting all homework assignments. Make sure your name appears in a comment in each of the revised .py files.  Put these files in a folder, and name it YourFirstInitialYourLastName.HW0 (for example, if I were a student I would name the folder HStraubing.HW0).  Compress the folder and submit the .zip file through Canvas.  Do not submit the .py files separately.

6. Optional Reading

Chapter 1 of the Think Python textbook is breezy reading.  (Make sure you've got the second edition!  The first is for Python 2.)
