Installation

pip install aio_process_pool

Usage

from aio_process_pool import ProcessPool, Executor

pool = ProcessPool()
executor = Executor()

def foo(x):
    return x

async def pool_example():
    return await pool.run(foo, 72)

async def executor_example():
    from functools import partial

    loop = asyncio.get_event_loop()
    return await loop.run_in_executor(executor, partial(foo, 74))

pool.shutdown()
executor.shutdown()

Demo

import asyncio
from aio_process_pool import Executor

def fib(n):
    if n <= 2: return 1
    return fib(n-1) + fib(n-2)

def fib_wrapper(n):
    print(f"fib({n}) = .....")
    result = fib(n)
    print(f"fib({n}) = {result}")

async def watch_htop_and_output_while_execution():
    exe = Executor()
    await exe.map_async(fib_wrapper, range(45))
    exe.shutdown()

asyncio.run(watch_htop_and_output_while_execution())
