[PyMOL] cmd.scene('*')

[Malcolm E D. <mal...@bm...>]

In a Python script I am working on I would like to get a list of the 
scenes that are defined.  Unfortunately, cmd.scene('*') just prints the 
list to stdout, but doesn't return anything.  That is, if I have a 
script test.py that looks like

> from pymol import cmd
> x = cmd.scene('*')
> print x


And I type "run test.py" in PyMol I get the following output

> PyMOL>run test.py
>  scene: stored scenes:
>   F1  F2
> x='None'


Is there a different mechanism to get a list of defined scenes?  Or an 
argument, I've missed?

 I have the following work around

> from pymol import cmd
> import sys
> from StringIO import StringIO
>
> tmp = StringIO()
> (tmp,sys.stdout) = (sys.stdout,tmp)
> cmd.scene('*')
> (tmp,sys.stdout) = (sys.stdout,tmp)
> list = tmp.getvalue().split("\n")[1].split()
> print list

which generates what I want

> PyMOL>run test.py
> ['F1', 'F2']

but that seems less than elegant.
