Someone else actually got me some help, the end result he hooked me up with was:
# function to evaluate all possible IPs
def findIPs():
ipFile = open("IPList.txt", 'w')
for octet1 in range(256):
for octet2 in range(256):
for octet3 in range(256):
for octet4 in range(256):
ipAddress = '%03.d.%03.d.%03.d.%03.d\n' % (octet1, octet2,octet3, octet4)
ipFile.write(ipAddress)
ipFile.close()
# execute the function
findIPs()
Thanks though, your response helps me understand variables better now..

Ahh. In the future, it will help us help you, if you make it clear that
there was an error, and *paste the exact error* into your mail.
For example, I'm guessing the error you got is:
>>> len(255)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
TypeError: len() of unsized object
As Robert said, this is because integers don't have a length.
James' suggestion to use string formatting is probably the "best"
solution, but the formatting codes are fairly daunting for someone never
exposed to them.

You know intuitively that strings *do* have length, and you appear to
know how to create a string from an integer. So the easiest
modification to your code to make it work wolud be something like:
mySet = str(x)
if len(mySet) == 1:
mySet = '00' + mySet
elif len(mySet) == 2:
mySet = '0' + mySet
Now, this can be made a little more elegant (and generalized) by using
the algorithm "if the string is too short, keep prepending zeros until
it's long enough."
target_length = 3
mySet = str(x)
while len(mySet) < target_length:
mySet = '0' + mySet
But this isn't as efficient as your solution. Once you know about the
interesting ability to multiply strings ("0" * 3 = "000"), you can
create a solution that's general, elegant, and efficient:
target_length = 3
mySet = str(x)
mySet = '0' * (target_length - len(mySet)) + mySet
