Runnable Class in Python

This project demonstrates a powerful way to chain functions together using a class called Runnable.

This project was inspired by runnables in LangChain Expression Language (LCEL).

Overview

The Runnable class is defined in main.py. It represents a function that can be run, and it provides a mechanism to chain multiple functions together using the bitwise OR operator (|).

Usage

Here's an example of how to use the Runnable class:

from main import Runnable

def add_five(x):
    return x + 5

def multiply_by_two(x):
    return x * 2

def square(x):
    return x * x

add_five = Runnable(add_five)
multiply_by_two = Runnable(multiply_by_two)
square = Runnable(square)

x = 5

# Using the Runnable class, we can chain functions together
print((add_five | multiply_by_two | square)(x))

In this example, we first define three functions: add_five, multiply_by_two, and square. We then wrap each function in a Runnable instance.

We can then chain these functions together using the | operator. The result is a new Runnable that, when called, will call the first function, pass its result to the second function, and so on.

For example, (add_five | multiply_by_two | square)(x) is equivalent to square(multiply_by_two(add_five(x))).

Installation

To use this project, you need to have Python installed on your machine. You can then clone this repository and run main.py.
