String arguments¶. F2PY generated wrapper functions accept (almost) any Python object as a string argument, str is applied for non-string objects. Exceptions are NumPy arrays that must have type code ‘c’ or ‘1’ when used as string arguments.. A string can have arbitrary length when using it as a string argument to F2PY generated wrapper function.

F2py allows you to automatically construct an extension module that interfaces to routines in Fortran 77/90/95 code. It has the ability to parse Fortran 77/90/95 code and automatically generate Python signatures for the subroutines it encounters, or you can guide how the subroutine interfaces with Python by constructing an interface-definition-file (or modifying the f2py-produced one).

Fortran assumed shape array and size function support in “numpy.f2py“ —– F2py now supports wrapping Fortran 90 routines that use assumed shape arrays. Before such routines could be called from Python but the corresponding Fortran routines received assumed shape arrays as zero length arrays which caused unpredicted results.
