OTOH, I don't find the python 3 "official" transition story very
convincing. I have tried to gather all the information I could find,
both on the python wiki and from transitions stories. To support both
python 2 and 3, the suggestion is to use the 2to3 script, but it is
painfully slow for big packages like numpy. And there ave very few
stories for porting python 3 C extensions.
Another suggestion is to avoid breaking the API when transitioning for
python 3. But that seems quite unrealistic. How do we deal with the
removing of string/long APIs ? This will impact the numpy API as well,
so how do we deal with it ?
Also, there does not seem to be any advantages for python 3 for
scientific people ?
