A try-catch block is used to mitigate errors in code and prevent program crashing during runtime. It 'tries' a block of code that could give an error. If the error (exception) is raised, it will execute a different block of code rather than crash the pro
2. 在try-catch语句中如何使用continue关键字 在Python中,continue关键字通常用于循环结构中,用于跳过当前迭代并继续下一次迭代。虽然continue不能直接在try-except块中使用,但可以在循环体内的try块中使用continue来跳过当前迭代。 当在try块中使用continue时,如果try块中的代码抛出异常且该异常被except块捕获,continue仍...

Explanation: In the above exercise, we have a division operation where the denominator is intentionally set to 0 to cause a division by zero exception. The code is wrapped inside a try block, and if an exception occurs within the try block, it is caught by the catch block. The catch blo...
