have you seen: https://github.com/pytoolz/toolz ?

Very cool, thank you! I’ll add toolz to the resources section.

Aren't exceptions already "railway oriented programming" in the way you describe it?

Specifically, there isn't any handling of this except at the top level

so the complaint about try except clutter seems misplaced

You’re right @U3JH98J4R - try-catch is a two rail system already 😄 I’ll try to rephrase and rethink this.

I have rewritten the “why”-part a bit: https://github.com/DavidVujic/pythonic-railway#why-railways

toolz looks like :star-struck: for a developer coding python. Very cool 😄
