Pyhandling

Library for advanced continuous handling of anything

Provides tools to extend single call logic on a nearly unlimited scale
You can even integrate the entire program logic into one call

Installation

pip install pyhandling

Example

from functools import partial
from typing import Iterable

from pyhandling import ActionChain, HandlingNode, Brancher, EventAdapter, ErrorRaiser, CollectionExpander, Mapper, return_
from pyhandling.checkers import Negationer, TypeChecker, Aller


main = ActionChain(
    HandlingNode(Brancher(
        EventAdapter(ErrorRaiser(TypeError("Input data must be iterable collection."))),
        Negationer(TypeChecker(Iterable))
    )),
    HandlingNode(Mapper(
        Brancher(
            EventAdapter(ErrorRaiser(TypeError("Elements of the input collection must be numbers."))),
            Negationer(TypeChecker(int | float))
        )
    )),
    CollectionExpander(range(11)),
    HandlingNode(print),
    partial(
        filter,
        Aller(lambda number: not number % 2, lambda number: number != 0)
    ),
    tuple,
    HandlingNode(print),
    partial(map, lambda number: number + 1),
    Brancher(tuple, TypeChecker(Iterable) | TypeChecker(int | float), return_),
    HandlingNode(print),
    sum,
    print,
    EventAdapter(exit)
)

if __name__ == '__main__':
    main(range(-10, 0))
