CSE 142: Computer Programming I, Autumn 2009

If you missed any of the python lectures in the past and you still would like to learn, then come to the python lecture this week. We will be reviewing all of the old material as well as introducing some new things.

Python Homework 6: You Choose
Due Tuesday, November 17, 11:30pm. Turn in Python HW6 here.

The assignment: Turn in one of the previous homework assignments if you didn't get a chance to before. The reward for this program is 1 extra late day. Instructions: for you first file, name it review.py. Any subsequent homeworks should have the name of the assignment such as song.py or guessing_game.py.

Python Homework 5: Guessing Game
Due Saturday, November 7, 11:30pm. Turn in Python HW5 here.

The assignment: Turn in a file guessing_game.py containing a Python version of your HW5 guessing game program. The reward for turning in this program is 1 extra late day for use on your normal Java programs.

For an extra challenge: implement a two-dimensional guessing game, still named guessing_game.py, according to these specifications.

The program will look like this:

This program is a 2-D guessing game.
I will think of a point somewhere
between (1, 1) and (20, 20)
and give hints until you guess it.

Guess x: 5
Guess y: 7
You're cold. Go south east
Guess x: 18
Guess y: 5
You're cold. Go south west
Guess x: 15
Guess y: 2
You're warm. Go north west
Guess x: 12
Guess y: 3
You're hot! Go north west
Guess x: 11
Guess y: 4
You got it right in 5 guesses!

Overall results:
Games played  = 1
Total guesses = 5
Guesses/game  = 5.0

More sample output:

Test 1 | Test 2 | Test 3 | Test 4 | Test 5

Python Homework 4: Birthday
Due Sunday, November 1, 11:30pm. Turn in Python HW4 here.
No late turnins accepted.

The assignment: Turn in a file birthday.py containing a Python program that produces output such as the output below. The task is identical to the Java HW4 except that you will also print out the user's astrological sign such as Leo or Virgo. At the bottom of your program, you should print an interesting fact about your own astrological sign, or your sign's current horoscope. Check here to find the date ranges for each sign, or look at the following table:

The following is an example output from your program. Notice that for simplicity, the month and day are read on separate lines.

This program tells you how many days
it will be until your next birthday.

Please enter today's date:
What is the month (1-12)? 7
What is the day   (1-31)? 24
7/24 is day #205 of 365.

Please enter your birthday:
What is the month (1-12)? 11
What is the day   (1-30)? 6
11/6 is day #310 of 365.

Your next birthday is in 105 days.

You are a Scorpio.

Python Homework 3: Circles
Due Sunday, October 25, 11:30pm. Turn in Python HW3 here.
No late turnins accepted.

The assignment: Turn in a file circles.py (lowercase c) containing a Python version of your HW3 Circles program that produces the output shown below, essentially the same as the Java version but drawn in Python. The window size and coordinates of all drawn figures are the same as in the Java version. As a reference, our sample solution is 40 lines long. The reward for turning in this program is 1 extra late day for use on your normal Java programs.

You won't be able to check your output since our Python DrawingPanel doesn't know how to compare images. But we will be lenient on whether the graphical output exactly matches. If you like, you can play around a bit with the exact colors and coordinates to produce a figure you like better, so long as the overall appearance closely matches the above screenshot.

Producing the above output will count for full credit, but if that sounds too easy for you and you want an added challenge, you can instead make your circles.py program produce the output below, drawing "globe" figures instead of the normal target figures. This is harder, but probably not as hard as it looks! Read below to see how to do it.

The main change between this globes program and the Java Circles version is that rather than drawing concentric circles in each subfigure, this version draws two sets of contentric ovals that give each subfigure a "globe-like" appearance. In one set, all ovals have equal heights but varying widths. The other set have equal widths and varying heights. In both cases, the amount of change in oval size is the same as the "gap" from the Java HW3-Circles assignment. The dimensions and counts for this assignment are identical to those of the Java HW3 assignment.

The other change from the Java program is that the colors of each subfigure and grid have been parameterized. Use string parameters to represent the colors used in the screenshot, such as orange (top-right), red (bottom-middle), and blue (bottom-right). Use default parameter values and/or parameter keywords as appropriate.
