Option and Result types for Python.

isos

isos is a Python library that introduces Option and Result types to implement the "result pattern" in your code.

Why Use This Pattern?

In traditional Python, errors are handled with exceptions. The result pattern takes a different approach by treating errors as values that can be:

• Passed between functions
• Transformed
• Chained together
• Explicitly handled at the appropriate point

This forces developers to consciously handle non-existent values and error conditions, leading to more robust and predictable code.

Core Features

• Option Type: Explicitly represents the presence or absence of a value
• Result Type: Represents either a successful value or an error value
• Custom Errors: Create your own error types by subclassing the Error class

By making errors first-class citizens in your code, isos helps prevent bugs that might occur from unhandled edge cases and makes your error handling strategy more transparent and systematic.
