# Description

A few examples to illustrate the main steps required to build and call Fortran code from Python with the following tools:

| Tool | Pros | Cons |

| ---  |:---: |:---: |

| [ctypes](https://docs.python.org/3/library/ctypes.html) | 
Allows for tailor-made wrappers.
 
C-API as byproduct.
 | 
C-bindings and Python-bindings must be written for all data types and procedures (besides the manual effort, some aspects are not intuitive at all).
 |

| [f2py](https://numpy.org/doc/stable/f2py/index.html) | 
Little/no manual work.
 
Fortran procedures are automatically given a Pythonic signature.
 
Array dimensions become optional arguments.
 | 
No support for derived data types, abstract interfaces, etc.
 
No possibility for wrapper customization.
 |

| [f90wrap](https://github.com/jameskermode/f90wrap) | 
Support for derived data types, abstract interfaces, etc.
 
Can parse Doxygen (but not FORD) docstrings.
 | 
Procedure signatures remain unchanged (Fortranic, not Pythonic).
 
Procedures with callbacks are excluded (bug?).
 
Support seems limited (just an impression).
