I highly recommend you have a look into ipython. It is a breeze to work
with. I usually have a couple of terminal screens open, one with the
ipython interpreter, which helps me a lot when testing code snipplets.
You can install it using yumex, or just run 'yum install ipython' from
the root comma
Thanks, Alan. That's exactly the kind of explanation I was looking
for. As this is pretty much a one-off project and the data
transformations are pretty different for each field, I'll stick with
the functional approach. The rule of thumb you mention is useful,
too. I hadn't heard that befor

The Unix servers are ancient HP-UX ones. I doubt if

Surely if the file is compiled it can just run (and

The string is being used in a call to cursor.execute. The email_id is a
second parameter getting passed to execute. That is the *correct*
approach to use.

The book is slightly different and has some extra chapters but it
is now quite out of date, I recommend the web version (which
also has a lot of material not in the book, so swings and
roundabouts there.
