Part 2 Programming exercises. Answers

1. modify cgiplogon.py to display a link to your personal web page.

   Submit "week3q1.py" after you finished.

2. Given the program slider.py in tutorial folder, modify the code to add two buttons; one to reset puzzle to its initial position, and one to randomize the puzzle.

3. Write a Python program to implement a simple billing system for a company. Each line of the input data file for the billing system contains a name, address, transaction type, and amount of transaction separated by a "_". The transaction type is either C (for credit) or D (for debit). The transaction amount is given in dollars and cents. If we assume each person's balance is initially zero, that a credit reduces the balance, and a debit increases the balance, the computer program should produce a report, ordered on name, giving the final balance in dollars and cents in each account. If a balance is exactly zero, then that person's balance should not appear in the report.

   Example input:
   Fred Chan_213 Yuen Long Avenue_D_41.03
   Sue Wong_9102 Kowloon Circle_D_10.00
   Fred Chan_213 Yuen Long Avenue_C_0.01
   Baba Li_2000 E. 21st Street_D_450.00
   Sue Wong_9102 Kowloon Circle_C_5.50
   Jay Law_9103 Problem Area_C_25.00
   Fred Chan_213 Yuen Long Avenue_C_41.02
    
   Example output:
   Name		Address	                Balance
   ----		-------	                ------
   Baba Li         2000 E. 21st Street     450.00
   Jay Law         9103 Problem Area       -25.00
   Sue Wong        9102 Kowloon Circle       4.50
