5.1 安全性深度剖析:捍卫模板渲染的最后一道防线 模板引擎作为动态生成内容(尤其是HTML)的核心组件,其安全性直接关系到整个Web应用的安危。如果模板引擎处理不当,很容易引入严重的安全漏洞,其中最臭名昭著的便是跨站脚本攻击 (Cross-Site Scripting, XSS)。本节将深入剖析模板安全的核心议题,重点已关注XSS的成因、防范...

Back to normal. ① 上下文管理器是LookingGlass的一个实例;Python 在上下文管理器上调用__enter__,结果绑定到what。 ② 打印一个str,然后打印目标变量what的值。每个print的输出都会被反转。 ③ 现在with块已经结束。我们可以看到__enter__返回的值,保存在what中,是字符串'JABBERWOCKY'。

我更新了“contextlib 实用工具”,涵盖了自 Python 3.6 以来添加到contextlib模块的一些功能,以及 Python 3.10 中引入的新的带括号的上下文管理器语法。 让我们从强大的with语句开始。 上下文管理器和 with 块 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。
Python code is simple, short, readable, intuitive, and powerful, and thus it is effective for introducing computing and problem solving to beginners. Beginners are motivated to learn to program so they can create graphics. A big reason for learning programming using Python is that you can start...
