#test.py
class FileLikeObject(object):
def __init__(self,current_stdout):
self.data = []
self.oldstdout = current_stdout
def write(self,arg):
if arg != '\n':
self.data.append(arg)
def output(self):
sys.stdout = self.oldstdout
print self.data
sys.stdout = self

sys.stdout = f

f.output()
print "hi"
f.output()
