Getting output from "print" inside a function [duplicate]

Question

Im using a library of functions that some of them print data I need:

def func():
   print "data"

How can I call this function and get the printed data into a string?

If you can't change those functions, you will need to redirect sys.stdout:

>>> import sys
>>> stdout = sys.stdout
>>> import StringIO
>>> s = StringIO.StringIO()
>>> sys.stdout = s
>>> print "hello"
>>> sys.stdout = stdout
>>> s.seek(0)
>>> s.read()
'hello\n'
