Python file interface for strings [duplicate]

Question

Is there a Python class that wraps the file interface (read, write etc.) around a string? I mean something like the stringstream classes in C++.

I was thinking of using it to redirect the output of print into a string, like this

sys.stdout = string_wrapper()
print "foo", "bar", "baz"
s = sys.stdout.to_string() #now s == "foo bar baz"

Yes, there is StringIO:

import StringIO
import sys


sys.stdout = StringIO.StringIO()
print "foo", "bar", "baz"
s = sys.stdout.getvalue()

For better performance, note that you can also use cStringIO. But also note that this isn't very portable to python 3.
