> From the C-API you can do it. Of course you must fill it (at least with
None(s)) before returning it to python. See
> http://docs.python.org/c-api/list.html and in particular the note after
{{{PyList_New}}}. I don't know if it is doable directly in Cython without
calling the C-API.
Hi Simon !
Sorry for replying to myself but I should have said from the very
beginning
that I'm not a Cython expert ! I'm currently trying the {{{PyList_New}}}
version.
