redirection of standard output of a Python command to a Python variable

[TP]

Hi everybody,

I try to find a quick way to redirect the standard output of a Python
command (for example: print "message") to a python variable "foobar".
Ok, in this simple example, I could do foobar = "message", but in
fact 'print "message"' could be replaced by any Python function writing on
standard output.
I have googled on this subject.
To redirect to a variable, I could use a temporary file:

import sys
saveout = sys.stdout
fsock = open('out.log', 'w')
sys.stdout = fsock
print 'message'
sys.stdout = saveout
fsock.close()
fsock = open('out.log', 'r')
foobar = fsock.read()
fsock.close()
print "foobar= ", foobar

To redirect a system standard output directly to a variable (without
temporary file), I could do:

import os
f = os.popen("ls")
print f.read()
f.close()

But, how can I get the standard output of a Python command (print "message")
directly into a variable?

Thanks

Julien
