You can't flush it, but you can make it unbuffered. You can either force python to use unbuffered stdio: python -u myfile.py or you can get an unbuffered handle to the file import os, sys buffer_size = 1 new_stdin = os.fdopen(sys.stdin.fileno(), 'r', buffer_size) for c in new_stdin: do_something(c) though based on my reading, the first method works with both Py2 and Py3k while the second method doesn't reliably work in Py3k. -tkc -- https://mail.python.org/mailman/listinfo/python-list
