That should be pretty obvious: The UnboundLocalError comes up when you try to access a variable that hasn't been assigned a value before. E.g try this in an interactive python session: foo = "hello" print foo print bar # This will raise UnboundLocalError Now in your code, you have a conditional setting of diverse variables. So only if if 'Title' in line: title = line[6:-1] executes, a title is there. Later, you _always_ use title. So you have to do it like this: title = "Unknown" # or empty or whatever if 'Title' in line: title = line[6:-1] Then title will always be there. The reason that it works for _one_ but not for all is simply that by chance the one file _had_ a title, but at least one of all the files hadn't. So it crashes. If you'd only try that file, it would also crash with only one file. -- Regards, Diez B. Roggisch -- http://mail.python.org/mailman/listinfo/python-list
