concurrent.futures 是python3新增加的一个库，用于并发处理，提供了多线程和多进程的并发功能 类似于其他语言里的线程池（ CSDN开发助手，集成开发者常用工具，提升开发效率 See full list on blog.csdn.net concurrent.futures提供高层次的接口，用来实现异步调用。 这个异步执行可以使用threads（ThreadPoolExecutor）或者process（ProcessPoolExecutor） 这个feautre是Python3.2后的新功能，但是也支持Python2。 一 : 概述 concurrent.futures模块提供了高度封装的异步调用接口 ThreadPoolExecutor：线程池，提供异步调用 ProcessPoolExecutor: 进程池，提供异步调用 Both implement the same interface, which is defined by the abstract Executor class. from concurrent.futures import ThreadPoolExecutor, as_completed, wait, FIRST_COMPLETED from concurrent.futures import Future from multiprocessing import Pool # 未来对象，task的返回容器 # 线程池， 为什么要线程池 # 主线程中可以获取某一个线程的状态或者某一个任务的状态，以及返回值 # 当一个线程完成的时候我们主线程能立即知道 concurrent.futures.process.BrokenProcessPool: A process in the process pool was terminated abruptly while the future was running or pending. 小结 ：多线程不适合计算密集型，适合IO密集型，后面我会验证，多进程适合计算密集型。

This Java tutorial describes exceptions, basic input/output, concurrency, regular expressions, and the platform environment.
A Future represents the result of an asynchronous computation. Methods are provided to check if the computation is complete, to wait for its completion, and to retrieve the result of the computation. The result can only be retrieved using method get when the computation has completed, blocking if necessary until it is ready. Cancellation is performed by the cancel method. إحصائيات للقرصنة فيديو تعليمي بواسطة Jake Vanderplas على التحليل الإحصائي باستخدام فقط بعض المفاهيم الأساسية بما في ذلك المحاكاة ، وأخذ العينات ، خلط ، والتحقق من صحة عبر. concurrent.futures مورد تعليمي | 1) حُـوتُ 2) رَحِيقُ 3) حَـارِسُ 4) تُـوتٌ 5) فَـتِيـلُ 6) سِـتَـارَةٌ 7) حُــقُـولُ

Usually, the decision to use an interpreted language is based on time restrictions on development or for ease of future changes to the program.
