As much as I've dogged on Python in the past (significant whitespace, really?), I've got to admit that it's got some cool features too. For example, I'm playing with libpuzzle (a library for visually comparing images). It has a command line utility and a C and PHP API. Unfortunately, the CLI utility doesn't allow one to dump the raw comparison vector, and it's a PITA to write C just to play with a library. Python's native "ctypes" to the rescue! from ctypes import * class PuzzleCvec(Structure): _fields_ = [("sizeof_vec", c_size_t), ("vec", c_char_p)] class PuzzleCompressedCvec(Structure): _fields_ = [("sizeof_compressed_vec", c_size_t), ("vec", c_char_p)] class PuzzleContext(Structure): _fields_ = [("puzzle_max_width", c_uint), ("puzzle_max_height", c_uint), ("puzzle_lambdas", c_uint),
