Thanks for the help. Yes, I see now that gdbm is really superfluous.
Not having used pickel before, I started from the example in Python
in a Nutshell which uses anydbm. Using a regular file saves some
time. By far, the biggest improvement has come from using marshall
rather than cPickel.

I'm on this general topic, the guide mentions a pet peeve about
inserting more than one space to line up the = in assignment
statements. To me, lining them up, even if it requires quite a few
extra spaces, helps readability quite a bit. Comments?

Thanks for the responses.
The point about 132 columns is good. Pretty much any printer will
handle that today, though I reserve the right to change my mind about
the utility of 17cpi print after I'm 50. Hopefully, all printers will
be at least 1200dpi by then. ;-)

A couple of off the wall questions.
It seems to me that there is usually a solid *reason* for things in
Python and I'm wondering about the rationale for the way slicing works:
my_string[2:5]

string because indexing starts at 0
Something like this should work:

for c in form.get('date'):
if c in string.letters:
print ERROR: You have to enter a date with numbers.

You have to import the string module. 'letters' is one of the
attributes defined in that module.

Kinda ugly, and I lifted it from an old post, but this should work:

finally:

Hi,
I am trying to come up with a clean and simple way to sort a list of

e.g. a Person object may have an age, a lastName, and a firstName.
I'd like to be able to arbitrarily sort by any combination of those in
