Always use the same method for writing, or you will get weird results.
If you think the above works, try:
          for char in 'sample': f.write(char)

class MultiWrite(object):

     def write(self, text):
         for dest in self._files:
             dest.write(text)

     def __init__(self, *files):
         self._files = files

     def close(self):
         for dest in self._files:
             dest.close()


f1 = MultiWrite(open('1.txt', 'w'), sys.stdout)
