[Tutor] sys.argv[1: ] help

[Liam Clarke]

Are you using XP still? I've never seen this before -  
> ./arg1.py a  b c

But anyhoo, I tried out just 
'c:\python23\foo.py'
as opposed to 
'c:\python23\python foo.py' and
while foo.py will run, it doesn't echo to the console, as on my
machine running a .py file runs it through pythonw.exe - I'd check it
out for your machine, it's probably the same. You'd need to change the
association to python.exe, but that would mean that you always got a
DOS box for every Python script you ran, which is annoying with GUIs.

Erm, if you don't want to type in python each time, either change the
association or create a batch file called x or a or something that
runs Python  and stick it in a directory that's in your PATH system
variable. Only problem with that is passing command line variables....

...might just be better to type python....

Good Luck, 

Liam Clarke
