Don't worry too much for the accessors, I'm pretty sure it won't degrade your performance in a noticeable way, you objects will only grow a tiny bit by adding a function to the class, all objects share the same in memory code and each one has it's own data, the function for the object is just a reference for the class function, not the memory of the function itself (I think, it would be a waste of memory otherwise).
However take it with a grain of salt, do your own benchmarks, you could do a simple measure with time.time() function, or use one of the several profiling modules for python (profile, hotshot, etc).
