Python-异步调用function（）吗？

Question

What's the shortest way to call a function asyncronously?

The user should always be able to input a new value; But each action() must be queued

def action(i):
   #takes a long time to be achieve

while True:
    i = raw_input("Input your value: ")
    action(i)

Answer 1

Use Multiprocessing module:

from multiprocessing import Pool

def action(i):
   #takes a long time to be achieve

worker_pool = Pool(processes=1)
while True:
    i = raw_input("Input your value: ")
    result = worker_pool.apply_async(action, [i], callback)

You can also use celery for background tasks:

@celery_app.task(bind=True,max_retries=None)
def action(i):
   #takes a long time to be achieve

while True:
    i = raw_input("Input your value: ")
    action.apply_async(args=[i])
