##I know I should be using 2.4 and os.Popen,
I know, I know… ##However, since most modules I need, I’m using 2.3
for this script I’m having troubles executing a shell script. The thing is that I’m produing
material and geometry files that need to be compiled to a binary description (for
those familiar to Radiance, oconv) The trouble I’m having is that when python goes
through my loop, files are overwritten before os.system
was able to process these! (who ways complaining
python is slow, well I’m not!! ;-) So the obvious thing to do is to swap os.system for os.spawnv. Here’s where I run into trouble. In my os.system version, I’m
perfectly able to pipe into another file, since the process has no real
connection to python whatsoever. Would someone be able to explain me how to do this, all the
tools I’m using for this script are unix-like
tools and heavily rely on piping. program =
'xform.exe' path =
'c:\Radiance\bin\' args = ['-t 0 8
0', 'wall0.rad', '>', 'wall0.TRANS.rad'] os.spawnv(os.P_WAIT, path, ('xform', args)) here’s the cmd error message: xform: cannot
find file ">" ##for your info I’m on win/xp,
python 2.3.4 Cheers, Jelle. |
