Description

This library provides a functional programming interface for Python.

Result

The Result monad handles the three most common cases in programming:

1. computation succeeded
2. computation failed
3. computation valid, but resulted in nothing

Examples

from fpinpy import Result

startValue = Result.of(1).map(lambda x: x + 1).forEachOrFail(lambda x: print(x))

Design

It is based on the work by Pierre-Yves Saumont in his books, Functional Programming in Java (2017) and The Joy of Kotlin (2019).
