运行该代码,我们将会看到类似以下的输出: Traceback (most recent call last): File "example.py", line 11, in main func2() File "example.py", line 7, in func2 func1() File "example.py", line 3, in func1 raise Exception("Error in func1") Exception: Error in func1 1. 2. 3. 4...
如果所有推送和弹出听起来让你感到困惑，请看一下Python调用堆栈的（Call Stack）相关解释。现在让我们介绍一个错误：如果您运行此代码，将引发异常：这是如何运作的？它就像上面介绍的那样，func3，func2和func1被推送到调用堆栈。然后在func1中有一个运行时错误，因为它试图除以零。这引发了异常：Exception是一种特...

异常栈(Exception Stack)是指在程序中发生异常时,异常信息沿着函数调用链逐层向上传递并保存的数据结构。它记录了异常发生的位置及其上下文的关系,可以告诉我们异常发生时的函数调用顺序和具体的调用关系。 为什么要打印异常栈? 在程序运行过程中,如果出现异常而没有得到及时的处理和定位,可能会导致程序崩溃或产生意外的...
Now, theprint()line is only called if no exception was raised. Ifprint()raises an exception, this will bubble up the call stack as normal. Theelseclause is often overlooked in exception handling but incredibly useful in certain situations. Another use ofelseis when code in thetryblock requir...
The rest of the line provides detail based on the type of exception and what caused it. The preceding part of the error message shows the context where the exception occurred, in the form of a stack traceback. In general it contains a stack traceback listing source lines; however, it wil...
