I spend all day in vim writing python, and I've got to agree that refactoring and completion are two of vim's weakest points(I have heard that ropevim is pretty good but I never got into it). I've had very poor luck getting omnicompletion to work to my satisfaction, but one thing that works very well for me is opening buffers for several files related to what I'm working on and just using <C-n> / <C-p> for basic completion. I always have a bpython console open to test bits of code and make sure I'm calling functions correctly. The one thing that I miss is being able to complete a function name and have a small window pop up with its arguments and documentation. I've tried writing some simple plugins for this but have never managed more than a hack of a solution. My system works incredibly well for me and I wouldn't use anything else, but many of my coworkers use totally different methods and I don't blame them.
