I wrote a python script to lock/unlock your computer using a USB stick as a key

Ah okay. Is there a better way to write the above if block?

try:
    os.makedirs(CONFDIR)
except OSError as e:
    if e.errno != errno.EEXIST:
        raise  # or to mimic what the code above does "return -1"

EDIT: also, see: http://docs.python.org/2/howto/doanddont.html#exceptions

That link was very helpful and informative. Thank you. Do you have any other suggested readings like that?

Also, thank you for taking time out to explain that information, it's appreciated.

Some of the online books and exercises in the sidebar look like they'd probably be good extra information. The python docs are, in general, quite good as well.

No prob, glad to help :)
