Best way to feed python script of a file

[absolut]

Hi!
I'm newbie in python.
I need to do a service/daemon in python that it's always executing and it should read of a file. These file contains lines of an application that are generated by an application (like a log).
Python script should manage the lines in order and do things.
What's the best way to achive that?
In unix I use bash and FIFO file but I don't know how it's the best way with python and windows.
Thanks!
