我还从他的帖子“接口和协议”中学到了很多,比较了typing.Protocol和zope.interface——一种早期用于在松散耦合的插件系统中定义接口的机制,被Plone CMS、Pyramid web framework和Twisted异步编程框架等项目使用,这是 Glyph 创建的一个项目。²⁸有关Python 的优秀书籍几乎可以定义为对鸭子类型的广泛覆盖。我最喜欢...

上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。
