2022-09-22

捕获多个异常

将异常类型放入元组之中即可：

1
try:
2
    ...
3
except (URLError, ValueError):
4
    log('Reason:', e)

捕获所有异常

1
try:
2
   ...
3
except Exception as e:
4
   ...
5
   log('Reason:', e)

捕获除了 SystemExit 、 KeyboardInterrupt 和 GeneratorExit 之外的所有异常，如果需捕获这三个异常，可修改为：

1
try:
2
   ...
3
except BaseException as e:
4
   ...
5
   log('Reason:', e)
