definitely you need to have the test code first (unittest or doctest)

then it's just a matter of running a shell script (or python script with 
subprocess) to check if the code generated any errors in any version.

The problem might be how to install multiple sub-minor version of python. 
I often see a machine with multiple minor versions, but have no idea 
whether multiple sub-minor versions could coexists.
