What's wrong with my except?
提问by lagarkane
I've got a SyntaxError on my except:
我有一个语法错误，除了：
try:
opts, args = getopt.getopt(sys.argv[1:], 'P:D:H:d:u:p:nvhmJi:c:Ml:TB:',
['host=', 'port=', 'directory=', 'user=', 'password=',
'daemon=', 'noauth', 'help', 'verbose', 'mysql',
'icounter=', 'config=', 'nolock', 'nomime', 'loglevel', 'noiter',
'baseurl='])
except getopt.GetoptError, e:
print usage
print '>>>> ERROR: %s' % str(e)
sys.exit(2)
I get the error:
我收到错误：
File "main.py", line 199
except getopt.GetoptError, e:
SyntaxError: invalid syntax
Anyone have any idea?

Your syntax is invalid for catching the exception
您的语法对于捕获异常无效
You should have written except getopt.GetoptError as e:instead of except getopt.GetoptError, e:
你应该写except getopt.GetoptError as e:而不是except getopt.GetoptError, e:
回答by georg
You use python3 and in python3 the raise syntax no longer accepts comma-separated arguments.
您使用 python3 并且在 python3中 raise 语法不再接受逗号分隔的参数。
Use asinstead:
使用as来代替：
except getopt.GetoptError as e:
This form is also backwards-compatible with 2.6 and 2.7.
这种形式也向后兼容 2.6 和 2.7。
