# Python中的多任务处理与并行 在现代软件开发中,提升应用程序的性能和响应能力至关重要。尤其在处理大量数据或进行复杂计算时,单线程的执行方式明显受限。在这种情况下,Python 提供了多任务处理和并行处理的多种方法。本文将解释这些概念,并给出相关的代码示例。 ## 1. 什么是多任务处理? 多任务处理(或称为并发)是指在同一程序中同时执行多个任务。它并不意味着这些任务在同一时间点完成,
多任务处理 多任务处理让人们在屏幕上(以及合适的iPad模式)查看多个app,而且在近期使用的app中高速地切换。在iOS 9中。人们能够使用多任务处理UI(例如以下所看到的)来选择一个近期使用的app。 在多任务处理环境中的成功取决于与设备上其它app的和谐共处。在高层面上。这意味着app应该:
