Reverse Multiplication Table

Question

I'm having troubling reversing my multiplication table.

This is what I have so far:

def reverseTable(n):
    for row in range(1, n+1):
        print(*("{:3}".format(row*col) for col in range(1, n+1)))

But I want to reverse it to:

25 20 15 10 5
20 16 12 8 4
15 12 9 6 3
10 8 6 4 2

Answer 1

You need to reverse your range so it counts backwards. The range() function accepts 3 parameters, range(start, stop, step) so to count from 10 to 1 you would use range(10, 0, -1)

Try this:

def reverseTable(n):
    for row in range(n, 0, -1):
        print(*("{:3}".format(row*col) for col in range(n, 0, -1)))

Answer 2

for row in range(9,0,-1):
    print(end="\t")
    for column in range(9,0,-1):
        print(row*column,end="\t ")
    print()
