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:
though based on my reading, the first method works with both Py2
and Py3k while the second method doesn't reliably work in Py3k.
