For example, in the following table, the upper limit is 15.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
2 4 6 8 10 12 14 16 18 20 22 24 26 28 30
3 6 9 12 15 18 21 24 27 30 33 36 39 42 45
4 8 12 16 20 24 28 32 36 40 44 48 52 56 60
5 10 15 20 25 30 35 40 45 50 55 60 65 70 75
6 12 18 24 30 36 42 48 54 60 66 72 78 84 90
7 14 21 28 35 42 49 56 63 70 77 84 91 98 105
8 16 24 32 40 48 56 64 72 80 88 96 104 112 120
9 18 27 36 45 54 63 72 81 90 99 108 117 126 135
10 20 30 40 50 60 70 80 90 100 110 120 130 140 150

Now let us develop a function that takes upperLimit as an argument and prints the multiplication tables. The
th th
multiplication table has 10 rows. The i row has an i multiple of each number in the range range (upperLimit+1).
So, the outer loop would run for each row, and the inner loop would run for column (col), and print. i*col
(see program 11.10). To make the table nice looking, we print each number using three column positions and use the
specification '{0:3}'.format(i*col) for printing. The statement print('{0:3}'.format(i * col),
end=' ') prints the product of i and col formatted to take up at least 3 characters (including digits and spaces). The
end=' ' parameter ensures that the values are separated by a space rather than a newline character. The numbers in
each row are separated by a blank. Once a row is complete, we transfer the print control to the next line by executing
a print statement (line 6). For details, please see program 11.10.

Program 11.10 Write a function multTables(upperLimit) to print the multiplication tables up to upper limit.

01 def multTables(upperLimit):
02 print('Multiplication Tables for ', 1, 'to', upperLimit)
03 for i in range(1, 11):
04 for col in range(1, upperLimit+1):
05 print('{0:3}'.format(i*col), end=' ')
06 print()
07 multTables(15)

Make use of Program 11.10 in a program to print multiplication tables of numbers from lowerLimit up
to a upperLimit, provided as input by the user. For example, for the numbers 3 and 6 provided as input
for lowerLimit and upperLimit, the program should yield the following output:

Multiplication Tables for 3 to 6
3 4 5 6
6 8 10 12
9 12 15 18
12 16 20 24
15 20 25 30
18 24 30 36
21 28 35 42
24 32 40 48
27 36 45 54
30 40 50 60
