Rust like Option type in Python

Option

A rust-like Option type in Python, slotted and fully typed.

An Option type represents an optional value, every Option is either Some and contains Some value, or NONE

Using an Option type forces you to deal with None values in your code and increase type safety.

Quick Start

from option import Some, NONE, Option
from requests import get

def call_api(url, params) -> Option[dict]:
    result = get(url, params)
    if result.status_code == 200:
        return Some(result.json())
    return NONE

# Instead of checking for None, the NONE case is always dealt with.
dict_len = call_api(url, params).map(len)

Install

Option can be installed from PyPi:

pip install option
