[Tutor] Flow of execution of execution

[William Becerra]

hey, I'm new to programming.
running Python 2.7.8 on windows 8 OS
Im on chapter 6 of a book called 'How to Think Like a Computer
Scientist-Learning with Python'
here is the code:
def printMultiples(n, high):
    i = 1
    while i<=high:
        print n*i, "\t",
        i = i + 1
    print
def multipleTable(high):
    i = 1
    while i<=high:
        printMultiples(i, i)
        i = i + 1
    print
print multipleTable(6)

when i run this code the result i get is

1
2 4
3 6 9
4 8 12 16
5 10 15 20 25
6 12 18 24 30 36

None


Can someone please explain why does it print a triangular table and not a
square table like this one:

1 2 3 4 5 6
2 4 6 8 10 12
3 6 9 12 15 18
4 8 12 16 20 24
5 10 15 20 25 30
6 12 18 24 30 36

None

is there any documentation i can read on tables?
Thank You
