Does anyone have a similar code in Python that they want to share? To determine the coefficients in a FDM.

Your post makes no sense.

It's 'divided differences'. Finite difference is different and talking about coefficients is nonsense in that case.
Have you checked numpy, scipy
https://docs.scipy.org/doc/numpy/reference/generated/numpy.diff.html
These techniques are highly unstable and ill-posed in general. Better not to use it. And I have never used it myself.
Out of curiosity, what's the problem to be solved?

Thank you Daniel..
Educational purpose only.. I am in quarantine from work so I have deicded to spend time learning numerical analysis. I managed to buy a copy of
Randy LeVeque -- Finite Difference Methods for ODEs and PDEs (the only book available at the university bookshop close to my home in Denmark, Copenhagen.)
I am simply trying to play around the concepts introduced in chapter 1 but I don't have Matlab license (too expensive).

Apologies for my brusque answer. It is important to keep the definitions clean.
I know Python has buckets of stuff and is free. (check out numpy, scipy).
Here's a nice ODE intro + Python.

As we speak I have just implemented a set of ODEs for Covid-19. See
