在Python中,我们可以使用Exception类来捕获所有异常。 try:result=1/0exceptException:print("发生了异常!") Python Copy 在上面的代码中,我们尝试将1除以0,这将引发ZeroDivisionError异常。在我们的except块中,我们使用Exception来捕获所有异常。无论引发的是哪种类型的异常,程序都会执行except块中的代码,并打印出相应...

示例如下：try:(tab)# Some code that may raise exceptions...except (ValueError, TypeError) and "error": # Rarely used, but possible.(tab)print("Multiple exceptions occurred.")在这个例子中，"and"用于连接多个异常类型和处理代码。当抛出多个异常时，将执行print语句。需要注意的是，"and"在异常处理...

Catching Specific Exceptions in Python For eachtryblock, there can be zero or moreexceptblocks. Multipleexceptblocks allow us to handle each exception differently. The argument type of eachexceptblock indicates the type of exception that can be handled by it. For example, ...
