清理引发的CustomException消息中的内部路径和堆栈级别 因为我们是在引发,而不是CustomException,所以我必须学习处理堆栈跟踪的新东西,堆栈跟踪不是作为引发的异常存在的,而是作为将被引发的异常,如果这有意义的话。我只想去掉CustomException的内部和处理程序提升者信息,只显示与调用引发异常的处理程序的调用者相关的信息。
In case of input that represents a clear bug in a template, raising an exception may still be better than silent failure which hides the bug. Here’s an example filter definition: def cut(value, arg): """Removes all values of arg from the given string""" return value.replace(arg, "...

Otherwise, the function raises a TypeError exception with an appropriate error message. To use NumberList, go back to your interactive session and run the following code: Python >>> from number_list import NumberList >>> numbers = NumberList([1.1, 2, 3j]) >>> numbers [1.1, 2, 3j] ...
