Redirection problem.

I'm having some problems with a simple redirection problem.
I want to write a function call it DoIt that executes a command
in a seperate process, and returns an error status when done.
I also want it to print to stdout the combination of what is written
in to stdout and stderr by the process.
For example:
if not DoIt("ls -R *"):
print "Exited with error."
else:
print "Exited with Success."
When executed the output ( sans stuff after # which are my comments
here) should look like:
dir1/f1 # normal listing
dir1/f2 # normal listing
dir2: Permission denied # process doesn't have read permission on that
directory
f3
f4
Exited with Success. # At least I think it should exit with success.
The problem I have is controling the two outputs, and the return code.
for example:
if I try
sout=os.popen(line,'r',0)
while 1:
b=sout.read(1)
sys.stdout.write(b)
if not b:
return sout.close()
The problem is squeazing at three conditions in.
TIA
