how to capture os.execvp into variable

[s99999999s2003]

hi
i am using this code to run a ps command in unix

def run(program, *args):
pid = os.fork()
if not pid:
os.execvp(program, (program,) + args)
return os.wait()[0]

run("ps", "-eo pid,ppid,args")

It runs fine, but i wish to store the results into a variable....how
can i do this ? I tried
to put ret=os.execvp(program, (program,) + args) but ret has no value
thanks

Do you mean you want the output of ps? That seems most likely. In that
case use os.popen.

p = os.popen("ps -eo pid,ppid,args")
output = p.read()
p.close()
