Python异步调用函数（）？

Question

异步调用函数的最短方法是什么

用户应始终能够输入新值； 但是每个action（）必须排队

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

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

Answer 1

使用多处理模块：

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)

你也可以用芹菜做背景任务：

@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])
