[New-bugs-announce] [issue16306] Multiple error line for unknown command line parameter

[Thiébaud Weksteen]

New submission from Thiébaud Weksteen:

Hi,

I've just came across an insignificant bug in the Python command line 
interface. When using an unknown parameter, the same error appears 
more than once:

$ python3 -a -z
Unknown option: -a
Unknown option: -z
Unknown option: -a
usage: python3 [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.
$ python -a -z
Unknown option: -a
Unknown option: -z
Unknown option: -a
usage: python [option] ... [-c cmd | -m mod | file | -] [arg] ...
Try `python -h' for more information.
