F2PY user guide and reference manual

The purpose of the F2PY –Fortran to Python interface generator– utility is to provide a connection between Python and Fortran languages. F2PY is a part of NumPy (numpy.f2py) and also available as a standalone command line tool f2py when numpy is installed that facilitates creating/building Python C/API extension modules that make it possible

• to call Fortran 77/90/95 external subroutines and Fortran 90/95 module subroutines as well as C functions;

• to access Fortran 77 COMMON blocks and Fortran 90/95 module data, including allocatable arrays

from Python.
