通过以上示例我们可以看出,sys.exc_info()获取了当前处理的exception的相关信息,并返回一个元组,元组的第一个数据是异常的类型(示例是NameError类型),第二个返回值是异常的value值,第三个就是我们要的traceback object. 有了traceback object我们就可以通过traceback module来打印和格式化traceback的相关信息,下面我们...
如果我们用美式英语描述这段代码,我们可以这样说:“In the try block, we attempt to convert a string to an integer. If a ValueError occurs, we catch this exception and print a warning message.” (在 try 块中,我们尝试将一个字符串转换为整数。如果发生 ValueError,我们捕获这个异常并打印一个警告消息。

图13-6。Exception类层次结构的一部分。¹¹①LookupError是我们在Tombola.inspect中处理的异常。②IndexError是我们尝试从序列中获取超出最后位置的索引时引发的LookupError子类。③当我们使用不存在的键从映射中获取项时,会引发KeyError。现在我们有了自己的Tombola ABC。为了见证 ABC 执行的接口检查,让我们尝试用一...
