• input/output
• declare (name / space allocation) and initialize (assign value to) variables
• iteration (looping)
• selection (decision / IF-THEN)
• comments

You must write a small program in Python that illustrates all FIVE of the above concepts.

To fulfill the "comments" concept, do the following:

• insert a comment at the top of your program that states the problem your code is solving.
• insert comments elsewhere in the code to point out to me where each of the other concepts is illustrated.

As an example, I have attached a small JAVA "gimme 5" program. HOWEVER, I expect you to come up with a more creative idea (similar in complexity to the Smart Cart last week) instead of just randomly using the constructs the way I have in the minimal Java program.

Some examples include: Play a "hi-lo" guessing game with the computer; break a simple "Caesar cipher"; implement a classic sorting algorithm like Bubble; determine if a string is a palindrome; convert a decimal number to another base of the user's choosing . . . get the idea???

The Evidence:

Submit the following:

• your source code in a form that I can read and cut/paste if I would like to run it myself
• a screenshot showing in a way that is obvious to me that your program has successfully run (that is, one reasonable test case)
