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...

as elif in try assert else is while async except lambda with await finally nonlocal yield 当前python最新版本号为3.12,目前有35个关键字,比旧版本多了2个与异步编程相关的关键字;另外还多了四个所谓的“softkeyword”,导入keyword库,除了有kwlist还多了一个softkwlist。
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:...
