在英文口语交流中,如果我们要描述这个情况,可以说"An exception is raised when the program attempts to divide by zero."(当程序试图除以零时,会抛出一个异常。)在这个句子中,“exception"对应的就是我们说的"异常”,“is raised"对应的是"抛出”。 至于更深入的异常机制和Python底层如何处理异常,我们将在后续...

Within the except block, developers can perform specific actions related to handling the exception, such as logging or cleanup. The noteworthy aspect of this example is the use of the raise statement without any arguments. This statement is employed to rethrow the caught exception, preserving its ...
Here the raise statement means, “throw the exception last caught”. This is a simple case, and I probably didn’t need to remind you of it. But a more sophisticated technique is to catch an exception in one place, and raise it again in another. ...
