except Exception as e: exceptions.append(e) if exceptions: raise ExceptionGroup("Multiple errors occurred", exceptions) 捕获ExceptionGroup 捕获ExceptionGroup与捕获其他异常类似,但是你可以处理组内的每个异常: try: operation() except ExceptionGroup as e: for exception in e.exceptions: print(f"Handling ...

try: raise ValueError() except ValueError: print("Value Error") except KeyError: print("Key Error") 输出: Value Error 一个except 语句也可以捕获多个异常。这些方法将在下面讨论。 使用逗号和括号来捕获多个异常 实现此目的的第一种方法是用逗号分隔例外并将其放在括号中。以下代码显示了如何。 try: ra...
oneexcept clause, to specify handlers for different exceptions. At most one handler will be executed. Handlers only handle exceptions that occur in the correspondingtry clause, not in other handlers of the sametrystatement. Anexcept clausemay name multiple exceptions as a parenthesized tuple, for ...
When you usetry…exceptin your code, it’s actually only capable of catching the first exception that occurs within thetryblock. If you try to raise multiple exceptions, the program will finish after handling the first exception. The rest will never be raised. You can show this using code ...
In this article we're going to be taking a look at the try/except clause, and specifically how you can catch multiple exceptions in a single line, as well as how to use the suppress() method. Both of these techniques will help you in writing more accessible and versatile code that adhe...
Handlers only handle exceptions that occur in the corresponding try clause, not in other handlers of the same try statement. An except clause may name multiple exceptions as a parenthesized tuple, for example: except (RuntimeError, TypeError, NameError): pass Note that the parentheses around ...
