Week 0, Problem 2: Rochambeau
[30 points; individual or pair]

A rock, paper, scissors program -- that never loses...

This second problem asks you to practice

• creating new python files (in this case, by copying old ones)
• writing a bit of your own code (by altering another program, if you wish)
• textual input and output in Python

The idea is this: alter the program in hw0pr1.py so that it invites the user to play a game of "rock-paper-scissors." What's more, the program should make sure that it always wins the game (taunting the graders who will be running your program is optional).

Creating a new file named hw0pr2.py

• To create a new file named hw0pr2.py, first make sure you have hw0pr1.py (download it again, if necessary), and then copy-and-paste it to a new file. Rename that file to hw0pr2.py
• Do I really have to use that name?     Actually, no -- you can use whatever name you like for the homework assignment files, but when you submit them, you DO have to have them named as specified in the assignment. So, it's easiest to name them as the submission site is expecting from the very beginning.

How the program should work?

• The program should ask the user to choose rock, paper, or scissors. Then, it should repeat back to the user their choice, it should "reveal" its own choice, and then report the results. The program should always win -- of course, it will be cheating because it will know and use the opponent's input, but we will leave a true implementation of the game to next week. Briefly, in the game of rock-paper-scissors, rock defeats scissors, scissors defeat paper, and paper defeats rock.
• You may assume that the user will input one of rock, paper, or scissors. (But feel free to catch errors and report them, if you like!)
• You may write the dialog however you like, but here's an example dialog if you'd like one to follow. This is two distinct runs of the program:

>>>

Choose rock, paper, or scissors: scissors

You chose scissors - I chose rock

I win!

>>>

Choose rock, paper, or scissors: paper

You chose paper - I chose scissors

I win!

>>>

Submitting your hw0pr2.py file

• Once your program plays a flawless game of rock-paper-scissors, submit it at Canvas. Be sure to indicate the partner you worked with (if any).

On to "picobot"

The third and fourth problems on this assignment emphasize a very different way of thinking about computation. They don't use python, but a simulation called picobot. We will discuss it in the first week of EECS 110 classes.
