How to send EOF to Python sys.stdin from the command line? CTRL-D is not working

I am writing to my Python process from the command line on unix. I want to send EOF (or somehow flush the stdin buffer, so Python can read my input.)

If I press CTRL-C, I will get KeyboardError.

If I press CTRL-D, the program just stops.

How to flush stdin buffer?

If you use 'for l in sys.stdin', it is buffered.

You can use:

  while 1:
     l = sys.stdin.readline()

If this is not what is happening, you need to tell us more about what you are doing.
