Background

它在后台运行东西。

“围绕Python 3的concurrent.futures.ThreadPoolExecutor类的一个优雅的装饰器抽象”

—Simon Willison

此模块使得在您的应用程序后台运行东西变得极其简单，无论是命令行应用程序还是Web应用程序。

import time

import background


@background.task
def work():
    # Do something expensive here.
    time.sleep(10)


for _ in range(100):
    work()

import time

import background

# Use 40 background threads.
background.n = 40


@background.task
def work():
    time.sleep(10)
    return "Done!"

@background.callback
def work_callback(future):
    print(future.result())


for _ in range(100):
    work()

$ pipenv install background
