Here we focus on practical examples with minimal theory, so you can see how these blocks work in real-world scenarios.Example 1: Basic 'try-except' BlockIn this example, the conversion of the string "100" to an integer succeeds, so the 'except' block is never executed. The 'try' ...
“在我们写Python脚本的时候,总是会幻想着一步到位,代码如丝滑般流畅运行,这就需要我们预先考虑各种场景,然后对可能会出现的问题进行预先处理,而识别与处理各类问题(异常),常用的就是标题所说的——Try,Except,and Assert。本文针对这三个关键词,举了一系列的栗子,可以具体来看看。 The dream of every software ...
