Python-異步調用function（）嗎？

Question

異步調用函數的最短方法是什么？

用戶應始終能夠輸入新值； 但是每個action（）必須排隊

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

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

Answer 1

使用多處理模塊：

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)

您也可以將芹菜用於后台任務：

@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])
