如果当try后的语句执行时发生异常,python就跳回到try并执行第一个匹配该异常的except子句,异常处理完毕,控制流就通过整个try语句(除非在处理异常时又引发新的异常)。 如果在try后的语句里发生了异常,却没有匹配的except子句,异常将被递交到上层的try,或者到程序的最上层(这样将结束程序,并打印缺省的出错信息)。 如...
Python 单元测试详解 本文直接从常用的Python单元测试框架出发,分别对几种框架进行了简单的介绍和小结,然后介绍了 Mock 的框架,以及测试报告生成方式,并以具体代码示例进行说明,最后列举了一些常见问题。 一、常用 Python 单测框架 若你不想安装或不允许第三方库,那么unittest是最好也是唯一的选择。反之,pytest无疑是...

Furthermore, the inner functions aren’t defined until the parent function is called. They’re locally scoped to parent(), meaning they only exist inside the parent() function as local variables. Try calling first_child(). You’ll get an error:...
