Question

I have an instance of a Connection (required to DB API 2.0-compliant), but I don’t have the module from which it was imported. The problem is that I am trying to use named parameters, but I don’t know which paramstyle to use.

Since paramstyle is a module-level constant, I can’t just ask the Connection. I tried using inspect.getmodule() on my Connection instance, but it just returned None. Is there an easier way that I’m just missing, or will I need to do some try/except code to determine which paramstyle to use?

Answer 1

Pass type(connection) (connection class) to inspect.getmodule(), not connection object. The class tracks the module it was defined in so inspect can find it, while object creation is not tracked.
