I haven't tried playing with it myself yet, but this stood out to me.
The indentation is correct, but with the open quote that's a lot of
spaces. If it's supposed to be a new line then
ctypes.util.find_library('m') should be all the way on the left. I'm not
sure how python handles the extra spaces in .py files.
