For a bit on exception handling in general, check out the section
within the Python tutorial: http://docs.python.org/tutorial/errors.html.
As far as the ftplib module goes, it has an attribute named
'all_errors.' It's a tuple that contains all of the Exception types
that ftplib.FTP methods will throw. You can do something like the
following:

try:
   FTP_instance.do_something()
except ftplib.all_errors, e:
   handle_an_error(e)

I do something much like that in an NMS-like application I wrote.
