Getting a memory address

[FlamingoRider]

Hello. I know that this is probably going to be a really simple question but this is my first program that I'm trying to write in any program and I'm stumped. It's very short:

counter = 0

def letterSwitch1():
    while counter <= number:
        print "A" * number
        print "B" * number
        counter = counter + 1
        return

number=raw_input("Enter a number: ")

print letterSwitch1

After I enter a number when running it I get: function letterSwitch1 at 0x00B3AFB0

I'm running XP and Python 2.6 using Cream/VIM

I do not understand the purpose of the function letterSwitch1(). After making a few minor changes, it does something:

def letterSwitch1():
    # move variable counter into function body
    counter = 0
    while counter <= number:
        print "A" * number
        print "B" * number
        # use augmented addition
        counter += 1
    # change indentation so while loop will comnplete
    # return statement is not required, function will return None anyway
    return
 
# raw_input returns a string, type cast to int
number=int(raw_input("Enter a number: "))

# No need to use print statement here
# Add () to make function call
letterSwitch1()

Output:

>>> AAAAAA
BBBBBB
AAAAAA
BBBBBB
AAAAAA
BBBBBB
AAAAAA
BBBBBB
AAAAAA
BBBBBB
AAAAAA
BBBBBB
AAAAAA
BBBBBB
>>>

Well, that was quite simple, I feel kinda stupid for not figuring it out myself. Thank you very much.
