Functional Error Handling in Python
summary
A tiny Pythonic library implements Option Try Either inspired by Scalaz, used to replace seven-deep nested ifs and multiple try/catch exits in a fixed‑length parser; class construction makes a Try instantiation return the proper Success/Failure child type on exception; generator comprehensions implement a do construct that composes flatMap/map logic so composed parses short‑circuit on first failure; library is pip‑installable and the rewrite improves readability and error flow without changing surrounding Python usage.
