what's faster: merging lists or dicts in python?

I'm working with an app that is cpu-bound more than memory bound, and I'm trying to merge two things whether they be lists or dicts.

Dynamically setting the queryset of a ModelMultipleChoiceField to a custom recordset

I've seen all the howtos about how you can set a ModelMultipleChoiceField to use a custom queryset and I've tried them and they work.

I was hoping that using a di...
