来自an answer to a similar question：

You can completely remove buffering from stdin/stdout by using python's -u flag:

-u     : unbuffered binary stdout and stderr (also PYTHONUNBUFFERED=x)
         see man page for details on internal buffering relating to '-u'

and the man page clarifies:

  -u     Force stdin, stdout and stderr to  be  totally  unbuffered.   On
         systems  where  it matters, also put stdin, stdout and stderr in
         binary mode.  Note that there is internal  buffering  in  xread-
         lines(),  readlines()  and  file-object  iterators ("for line in
         sys.stdin") which is not influenced by  this  option.   To  work
         around  this, you will want to use "sys.stdin.readline()" inside
         a "while 1:" loop.

除此之外，它还没有得到（良好的或广泛的）支持。在
