Example 4: Printing a multiplication table.

Assume we want to print the following:

1 * 1 = 1
2 * 1 = 2  2 * 2 = 4
3 * 1 = 3  3 * 2 = 6  3 * 3 = 9
4 * 1 = 4  4 * 2 = 8  4 * 3 = 12  4 * 4 = 16
5 * 1 = 5  5 * 2 = 10  5 * 3 = 15  5 * 4 = 20  5 * 5 = 25
6 * 1 = 6  6 * 2 = 12  6 * 3 = 18  6 * 4 = 24  6 * 5 = 30  6 * 6 = 36
7 * 1 = 7  7 * 2 = 14  7 * 3 = 21  7 * 4 = 28  7 * 5 = 35  7 * 6 = 42  7 * 7 = 49
8 * 1 = 8  8 * 2 = 16  8 * 3 = 24  8 * 4 = 32  8 * 5 = 40  8 * 6 = 48  8 * 7 = 56  8 * 8 = 64

rows = 9
for row in range(1,rows ):
   for column in range(1,row + 1):     #For each row, the number of columns is
                                       #equal to the row number.
       print row, 		#The comma(,) here means no new line after printing
       print '*',
       print column,
       print '=',
       print str(row*column)+' ',  #Print the product and add a space in the end
   print   			 #When the row has been printed, go to the new line.
