How to control I/O buffering besides -u?

[kj]

Is there any way to specify unbuffered I/O from *within* the code
(rather than via the command-line -u flag)?

TIA!

When creating a file object, specify a buffer size of zero. I don't
know how to change the buffering of a file object that's already been
created, as stdin, stdout, and stderr are.

You can try flushing, or reopening with no buffering

sys.stdout.flush()
sys.stdout = os.fdopen(sys.stdout.fileno(), 'w', 0)
