CIS115 Week 4 Lab Overview


Title of Lab: Multiplication Table in Python


Summary
This week's lab is to create a simple multiplication table using nested loops and if statements.
Prompt the user for the size of the multiplication table (from 2x2 to 10x10). Use a validation loop to display a warning if the number is less than 2 or greater than 10 and prompt the user to enter the data again until they enter a valid number.
Put a # after any even number in your table (odd numbers will have just a space/nothing after them).


Deliverables
• A source code Python file.
• A Word document containing both source code and the screen print of the program outputs.


Lab Steps


Sample Output:
The output should be something similar to the following.
What size multiplication table would you like? (2 - 10): 1
Invalid entry - Enter a number between 2 and 10
What size multiplication table would you like? (2 - 10): 15
Invalid entry - Enter a number between 2 and 10
What size multiplication table would you like? (2 - 10): 10


--- Multiplication Table ( 10 x 10 ) ---
         1      2      3      4      5      6      7      8      9     10
---------------------------------------------------------------------------
1  |     1      2 #    3      4 #    5      6 #    7      8 #    9     10 #
2  |     2 #    4 #    6 #    8 #   10 #   12 #   14 #   16 #   18 #   20 #
3  |     3      6 #    9     12 #   15     18 #   21     24 #   27     30 #
4  |     4 #    8 #   12 #   16 #   20 #   24 #   28 #   32 #   36 #   40 #
5  |     5     10 #   15     20 #   25     30 #   35     40 #   45     50 #
6  |     6 #   12 #   18 #   24 #   30 #   36 #   42 #   48 #   54 #   60 #

8  |     8 #   16 #   24 #   32 #   40 #   48 #   56 #   64 #   72 #   80 #
9  |     9     18 #   27     36 #   45     54 #   63     72 #   81     90 #
10 |    10 #   20 #   30 #   40 #   50 #   60 #   70 #   80 #   90 #  100 #



Hints:
• The outer loop will start each new row.
• The inner loop will control the display of each column in the row.
• Note that to keep the numbers right-aligned, there are different amounts of space before single digit numbers (those less than 10), double digit numbers (those between 10-99), and triple digit numbers (100).
• The row labels can be added to your inner loop (note that there are different amounts of space required after the number in the row labels.
• The column labels should use a separate loop(s) that run before the main outer loop.
• You can continue printing on the same line using end="" in your print statement. This will come in handy if you want to print several things on one line inside a loop. For example, assuming the value of name is Ada, the following will print "Hello Ada" on one line:
print("hello ", end="")
print(name, end="")


Tips:
• Start early!
• Do the basic table first without worrying about spacing or lining things up, and don't include row or column headings (add those later).
• Once you get the numbers in the correct position, think about adding the proper amount of space before each number to line things up.
• Once the columns line up, add the #/space for even/odd numbers.
• Once the basic table is working, then add the row and column headings, and finally the main title.
• Test as you go!
