Precisely, it says:
-u : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x
see man page for details on internal buffering relating to '-u'
Note the "binary". And indeed:
./python -u
Python 3.1a0 (py3k:67839M, Dec 18 2008, 17:56:54)
[GCC 4.3.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import sys
>>> sys.stdout.buffer.write(b"y")
y1
>>>
I don't know what it would take to enable unbuffered text IO while keeping the
current TextIOWrapper implementation...
