Show HN: Katharos Functional programming and CSP-style concurrency for Python
Katharos is a new Python library that introduces functional programming paradigms and CSP-style concurrency to the language. It provides algebraic abstractions like Monads and Functors to help developers handle errors and side effects as type-safe values rather than exceptions.
A functional programming and concurrency library for Python. Katharos pairs algebraic abstractions ( Functor , Applicative , Monad , Semigroup , Monoid ) and concrete types like Maybe , Result , ImmutableList , and IO with message-passing concurrency built on the same functional core. The two halves share one idea: model errors, effects, and concurrent communication as composable, type-safe values . A concurrent hand-off returns a Result , so "the channel closed" is something you handle, not an exception you catch.
