# Sure.  This code does both.

class Mux:
    def __init__(self, *objects):
        self.__objects = objects
    def write(self, data):
        for obj in self.__objects:
            obj.write(data)
    def writelines(self, lines):
        for obj in self.__objects:
            obj.writelines(lines)

myfile = open('somefile.txt', 'a')
sys.stdout = Mux(sys.stdout, myfile)
