Since cython structures can be mapped from simple python dictionaries, we take an input of one, construct the structure on the fly in the function and then use our Fortran subroutine. The return type can also be coerced into a list, and that’s what can be printed or manipulated further. WebF2PY generated wrapper functions accept almost any Python object as a string argument, since str is applied for non-string objects. Exceptions are NumPy arrays that must have …
