Given that you are not using any libraries, let alone one that does not
run on Python 3, I strongly recommend using the latest version (3.3).

Your example below starts with 0, which is not positive.
Perhaps you mean that all integers after a single leading 0 have to be
positive and increasing.
If you run digits together, then the max int is 9. Do you intend this?

If users start the program at a command line, the core of an input
function would be
input = (raw)input('Enter digits: ') # Include "raw" on 2.x
You would need a more elaborate prompt printed first, and input checking
with the request repeated if the input does not pass the check.
It would be pretty simple to do the equivalent with a tkinter dialog box.

There are programs that will package your code with an interpreter. But
do give people the option to get just the program without installing a
duplicate interpreter.

>>> list('01112345')
['0', '1', '1', '1', '2', '3', '4', '5']
>>> '0,1,1,1,2,3,4,5'.split(',')
['0', '1', '1', '1', '2', '3', '4', '5']

On Linux, definitely, whether you have user enter on the command line or
in response to a prompt. On windows, it only helps with 3.3+.
