Hi, here you find version 27-12-2017 of 'sage_interface'.
Added string to numpy array conversion and some little improvements.

Feel free to propose improvements or changes to the code.
Have you good end and good beginning for the new year!
Bye

Because it uses depreciated functions, and more importantly functions which are not
supported on iOS. Technically, there might be a way to patch ctypes before you import to always return the same object, which you can then pre-patch to contain the faked method. On iOS dynamic loading is not allowed, so only static libraries that were compiled in are available, as well as NSBundles.

Using cwd helped -

DOCS_DIR = os.getcwd().split('Documents')[0] + 'Documents'
