I would create a data structure of the contents of the file and let the application reference that data structure. Sounds like it's going to be a list of lists or a list of dicts. Each line of the file is going to be an element of the "main" list. Each element of the list is going to be a dict or a list of the details of that particular host. Make it so that if your app changes the datastructure, you re-serialize it back to the file. This should work the same with adding a new host to monitor. It might be easier to use something like Yaml. I'm doing something similar with a little podcast grabber I'm working on. Here's some old code where I first incorporate using Yaml (down at the bottom of the page): http://jeremymjones.com/articles/simple-podcast-grabber-python/ The version I have in SVN right now creates a configgish object off of the Yaml and on re-assignment of either of the two main attributes, it automatically reserializes it. Anyway, hope this helps. - Jeremy M. Jones -- http://mail.python.org/mailman/listinfo/python-list
