Much as I prefer Python, I don't think that switching to it just for more security is going to be very satisfying or have a huge return.

I submit that security is typically more a function of your project than JUST the language it is written in. For example, I doubt that Haskell's focus on type safety alone will make your programs secure (particularly when you are not enjoying it and are spending more time than you want on issues other than security). You may get more bang for the buck by focusing on security as an issue within whatever language you are using?
