WebThe f2py method of linking compiled code is currently the most sophisticated and integrated approach. It allows clean separation of Python with compiled code while still allowing for separate distribution of the extension module. The only draw-back is that it requires the existence of a Fortran compiler in order for a user to install the code. 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 … small ag tractors

"WebF2PY parses Fortran/C signatures to build wrapper functions to be used with Python. However, it is not a compiler, and does not check for additional errors in source code, nor does it implement the entire language standards. Some errors may pass silently (or as warnings) and need to be verified by the user. The quick way # " - Cython f2py

The return type can also be coerced into a list, and that’s what can be printed or manipulated further.
