correct. > Is this indeed easier to maintain? yes, because while you can write C extensions in C, you need to use the quite complex Python/C api, and get all sorts of things like reference counting, etc right too -- that is hard. Also, with Cython, you can quite easily mix Python and C in one place, so you truly only need to put the performance intensive bits in Cython specific code. > When you would like to use legacy C code for an extension, would you > rewrite it in Cython? no -- you can call regular old C from Cython, so you can use it to write wrappers, too. > What are Cython's advantages compared to ctypes? for ctypes, you also avoid the wrapping code, but your C code needs to be compiled as a library, and can't use python types directly, which is more limiting. I think Cython is easier for someone not very experienced in C, and no harder for someone who is. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] _______________________________________________ Numpy-discussion mailing list [email protected] http://projects.scipy.org/mailman/listinfo/numpy-discussion
