Python 3.9 parser seems to be more accurate. I don't think that it's worth it to attempt to enhance Python 3.8 error reporting, since Python 3.9 got a whole new parser.


@apu$ python3.8 x.py 
  File "x.py", line 4
    open('file1', 'w') as file1,
                         ^
SyntaxError: invalid syntax


$ python3.9 x.py 
  File "/home/vstinner/x.py", line 4
    open('file1', 'w') as file1,
                                ^
SyntaxError: invalid syntax
