我正在运行别人的代码:
./run_me.sh
Traceback (most recent call last):
File "train.py", line 13, in <module>
import options
File "/Users/test/Desktop/lang-emerge/options.py", line 44
except IOError, msg: parser.error(str(msg));
^
SyntaxError: invalid syntax
我尝试修改except块,但再次出现错误:
./run_me.sh
Traceback (most recent call last):
File "train.py", line 13, in <module>
import options
File "/Users/test/Desktop/lang-emerge/options.py", line 44
except: IOError, msg: parser.error(str(msg));
^
SyntaxError: only single target (not tuple) can be annotated
错误所在的代码:
try: parsed = vars(parser.parse_args());
except: IOError, msg: parser.error(str(msg));
不知道该如何解决该错误? msg是python try / except块中的关键字。
使用修改后的代码IOError as msg:
我得到:
./run_me.sh
Traceback (most recent call last):
File "train.py", line 13, in <module>
import options
File "/Users/test/Desktop/lang-emerge/options.py", line 44
except: IOError as msg: parser.error(str(msg));
^
SyntaxError: invalid syntax
答案 0 :(得分:1)
except: IOError as msg: parser.error(str(msg));
您有不必要的冒号。您应该删除它:下面的代码是正确的代码。
except IOError as msg: parser.error(str(msg));
