Lab Assignment 4A

Printing out the times tables

For this lab only, you do not need to supply an algorithm. Complete as much as you can of the program.

Specification:

Your program asks the user for a number for which the times tables will be displayed. For example, if they enter the number 6, the following table is displayed:

1 x 6 = 6

2 x 6 = 12

3 x 6 = 18

4 x 6 = 24

5 x 6 = 30

6 x 6 = 36

7 x 6 = 42

8 x 6 = 48

9 x 6 = 54

10 x 6 = 60

After displaying the times table, the program should ask the user if they want to display another times table. The program continues as long as the user requests another table. Use a for loop to print the table and a while loop to repeat the program. See the powerpoint on repetition for example programs using while loops and for loops.

Implement your program in the Python language. Use the IDLE GUI to edit and run your program:

Your program should start with a comment block that contains the following information:

# File: yourstudentnumber.py

# Purpose: The times tables

# Programmer: [your name]

# Course: CSCI120A

# Date: Monday 29th September 2008

Before the start of the next class, save your program file (yourstudentnumber.py) to the following network:
