Which versions of Python and Blender are working well together now?
This should probably go under either the Questions or Python forum, but I guess while I’m here 
I believe that the way it works is prior to Blender 2.26 you should use Python 2.01, Blender 2.26 or later it is best to use Python 2.2 .
I could be wrong, I’m no Python expert; but that’s what I assume.
<Edit> Oh, I found the thread that I read regarding this, it’s:
https://blenderartists.org/forum/viewtopic.php?t=9627
</Edit>
The better question might be what Python script works with what Blender/Python version combination? Maybe this could be added to the Python script list, and maybe a guide for tweaking the scripts to work with the latest version as well could be added (Maybe not a good idea - What do you think?)
