Interfacing Fortran code from Python

I’m a Python programmer looking to Fortran as a way to speed up code that couldn’t be handled by array operations with Numpy and SciPy. (There are of course many other ways you can do this but I was also motivated to learn Fortran to understand legacy code in my field, computational chemistry). My goal would be to include Fortran code under the hood to handle slow operations for my Python packages. This code could be packaged for example by having separate Fortran packages included with git subm…

This thread should answer some of your questions, we started writing up some of the details for the different approaches but there is no final guide yet.
