How many of these steps have you attempted actually coding?  Seems to me 
your first two steps are just string manipulation, and you only need to 
use the datetime module if you need to validate.  In other words, if the 
user specifies the date as 31/09/2009, you might want to later bounce 
back to him with a complaint that September only has 30 days.


So the first task is to accept input in the form   ab/cd/efgh   and 
produce a string  efgh-cd-ab.log   which you will then create as a text 
file.  And if the file exists, you'll append to it instead of 
overwriting it.   Can you do that much?

Make sure each of these is in a function with a good name, so you can 
later refine the behavior, like adding error checking.  So right now, 
you might code the function without error checking, and later add some 
validation, with error messages and new input query.
