It should be the other way around
self.popen = popen2.Popen3(["/usr/local/bin/python",
"-O", "myscript.py"])
Item [0] must be the path to the executable and items[1:] are the
arguments. See the Popen3._run_cmd() method in Lib/popen2.py
partially copied here:
<pre>
def _run_child(self, cmd):
if isinstance(cmd, basestring):
cmd = ['/bin/sh', '-c', cmd]
.....
try:
os.execvp(cmd[0], cmd)
finally:
os._exit(1)
</pre>
