Be careful with the quotation marks, too; consider the case that value
contains a quotation mark (or an apostrophe).

I don't know what kind of database and/or API you're using, but DB-API
compliant (Python PEP 249) libraries will put the right quotation marks
(if any) around your strings *and* quote any internal troublesome
characters correctly.

HTH,
