Lab Assignment 4

Printing out the times tables

Time allowed: 30 minutes

For this lab only, you do not need to supply an algorithm or pseudocode. 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: lab4.py

# Purpose: The times tables

# Programmer: [your name]

# Course: CSCI120A

# Date: Wednesday 2nd February 2005

At or before 10:40am, save your program file (lab4.py) to your folder on the network in:

CSCI120A\Week05\Lab04

Quiz 1 starts at 10:50 prompt when the Lab 4 folder will be locked.

Program points will be based on the following marking scheme:

Marking Scheme: CSCI120A - Assessed Lab - Lab 4 - Times Tables
