[python-uk] Here's a little test

[python-uk@python.org]

Thanks, Simon. 

First, the webbrowser module doesn't work. At all:

>>> webbrowser.open("news.bbc.co.uk", 1)
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "C:\Python22\lib\webbrowser.py", line 43, in open
    get().open(url, new, autoraise)
  File "C:\Python22\lib\webbrowser.py", line 223, in open
    os.startfile(url)
WindowsError: [Errno 2] The system cannot find the file specified:
'news.bbc.co.uk'
>>> br = webbrowser.get()
>>> br.open('news.bbc.co.uk')
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "C:\Python22\lib\webbrowser.py", line 223, in open
    os.startfile(url)
WindowsError: [Errno 2] The system cannot find the file specified:
'news.bbc.co.uk'
>>> br = webbrowser.get('windows-default')
>>> br.open('news.bbc.co.uk')
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
  File "C:\Python22\lib\webbrowser.py", line 223, in open
    os.startfile(url)
WindowsError: [Errno 2] The system cannot find the file specified:
'news.bbc.co.uk'
>>>

Second, the *args syntax is meaningless in this context. 'args' isn't a list
but a string.

The following are equivalent:

args = "stuff"
f(cmd, args)

args = ("stuff", )
f(cmd, *args)

I've tried calling os.execl in all sorts of ways from the interactive prompt
and it simply does not work. I can make it run a command but not get any
args. 

I thought this was going to be a simple conversion but I've spent bloody
hours on it :o(

First thought - what's wrong with the webbrowser module?

Second thought - have you tried os.execl(iepath, *args)?
