goroutine-py

🚀 An Asyncio-based concurrency library for Python.

Easy concurrency just like goroutine without worry about thread and coroutine in Python.

Introduction

Withing goroutine.app.go you can run a coroutine or a func asynchronously.

Main function go :

go (obj: callable, *args, callback: callable = None, lock: bool = False)

obj: Takes both callable coroutinefunction and func as object.

*args: Arguments for your obj.

callback: Attaches a callable that will be called when the future finishes.

Getting Started

Support:

Python 3.7 / 3.8 / 3.9 / 3.10 / 3.11 / 3.12

Installation

First you have to install goroutine-py like this:

pip install goroutine-py

Quick Tutorial

The primary entity of goroutine-py is goroutine.app.go.

You can simply start using goroutine-py like this:

First, define your tasks:

import asyncio
import time
from goroutine.app import go

# A normal func
def task_1(n=2):
    time.sleep(n)
    print('Task_1_done')
    return 'Result_1'

# A coroutinefunction
async def task_2(n=1):
    await asyncio.sleep(n)
    print('Task_2_done')
    return 'Result_2'

# Callback func
def callback(result):
    '''
    Parameter "result" is the return from task.
    Use functools.partial() to give arguments if you need more args at the beginning.
    '''
    print('-* callback *-')
    print(result)

After you defined all your tasks and callback, you can go like this:

go(task_1)
go(task_2)

# The "callback" parameter must be specified separately.
go(task_1, 5, callback = callback)
go(task_2, 3, callback = callback)
print('END')

# Forever runing to show results.
while 1:
    time.sleep(5)

Output :

>>>
END
Task_2_done
Task_1_done
Task_2_done
-* callback *-
Result_2
Task_1_done
-* callback *-
Result_1
