You have two choices:

1- Just get rid of the version number in the name (what's the point) and 
define a __version__ attribute in the module, that's what is usually done.
2- create a wrapper module called "" whose content will be 
something along the lines of "from your_current_module_with_version 
import *"

I'd strongly suggest the first choice, there is no point in giving the 
version number into the file name of a module.
