Oops, I meant '"Cython" is its own language,' not "Python" (although Python qualifies, too, just not in context).
Also, Pyrex, listed in the c-info.python-as-glue.html page, was the pre-cursor to Cython. -Bill On Oct 27, 2014, at 10:20 AM, Bill Spotz <wfsp...@sandia.gov> wrote: > Python is its own language, but it allows you to import C and C++ code, thus > creating an interface to these languages.
