Yep, I knew about struct but I did go for ctypes because... I wanted to try it and thought it would be a suitable solution (with more capabilities).
Looks like I fooled myself (not in the way ctypes is badly designed, it's just not what I needed).

Now I'm left with a dilemma:

My current ctypes code is working (thanks Peter !), but the code is rather cumbersome.

1/ don't change it, and wish good luck to my next co-worker looking at the code
2/ rewrite everything with struct
3/ rewrite everything with cffi (Laura's suggestion) which has the awsomeness to suppport C code copy/paste. It's still a "C Foreign Function Interface" like ctypes and could be overkill


We all know how this ends up...
