Sorry for my ignorance, but I've never edited email headers before and didn't find any relevant help on Google. Could you please give some more details about how to do what you're referring to, or perhaps point me to a link that would explain more about it? (FYI, I read the Python mailing list on Google Groups, and reply to posts in Thunderbird, sending them to the Python-list email address.)

I was thinking that since I've been manually calling conn.commit() in my wxPython program after executing each SQL transaction, it would make sense to use autocommit mode (by setting 'isolation_level' to None). Am I correct about this? I've read on StackOverflow that there can be disadvantages to using autocommit mode for SQL databases in general, but they weren't elaborated. The only one I could think of would be decreased performance if SQL transactions are committed automatically more than necessary (which wouldn't apply in my case). I guess that's also likely why PEP 249 specifies that Python database implementations must have autocommit mode turned off by default.

Thank you.
