Well, the easiest thing you can do is to wrap your offending code inside 
a try-clause, like so:

    try:
        offending_code
    except:
        deal_with_breakdown

If you really want to check the settings of the file, I guess you should 
read up on module os, and especially os.stat. Also, take a look at module
stat.

Good luck!
