I ran it in IDLE with Python 2.7.8 and got:

I believe that IDLE plays funny games with sys.stdout etc., so I'm not
surprised that this doesn't run under IDLE.

Just to be clear, writing to sys.stdout works fine in Idle.
 >>> import sys; sys.stdout.write('hello ')
hello  #2.7

In 3.4, the number of chars? bytes? is returned and written also.

Whether you mean something different by 'stdout' or not, I am not sure. 
  The error is from writing to a non-existent file descriptor.
The os 'file descriptor functions are unix functions.  Many but not all 
also work on Windows.  I do not believe that was true on msdos. 
According to the os doc, they do not work on osx.  Python io streams are 
not required to have a file descriptor.

Only for narrow minded ascii users (Like plenty of other
stuff in Python).

That's because sys.stdout is replaced. But stdout itself, file
descriptor 1, is not available:

>>> os.fdopen(1,"w").write("Hello, world\n")
Traceback (most recent call last):
  File "<pyshell#4>", line 1, in <module>
    os.fdopen(1,"w").write("Hello, world\n")
OSError: [Errno 9] Bad file descriptor

This works fine in command-line Python, just not in IDLE. It's not
Windows vs Unix, it's Idle vs terminal.

Yes, just tested it on the same machine in the terminal and it prints:

Hello, world!
13

Not sure what the 13 is all about. Thanks.

Actually, there is no comma after Hello.

Number of bytes output. It's the return value from the output call -
common with low-level APIs.

I don't trust sudo because it is too complicated.
(To the point that I removed it from my machine.)
I do
su
..
#
su nobody

Who needs sudo?

It's like instead of telling a 4-year old to stay on the
side walk, learning him to read and then give him a 8-page
brochure about "safety in traffic".

With sudo, you get MUCH finer control. I can grant some user the power
to run "sudo eject sr0", but no other commands. I can permit someone
to execute any of a large number of commands, all individually logged.
I can allow sudo to other users than root, without having to reveal
those accounts' passwords (chances are they don't even have
passwords).

But sure. If you want to cut out complication, dispense with user
accounts altogether and run everything as root. That's WAY simpler!

You've answered   it. sudo works for a system with a very
knowledgeable system administrator and at least one other user.
Not for an electronic engineer who uses Python on his Raspberry Pi.

I've no problem explaining to an electronic engineer not to do this,
while not offering him to do the system administration for him.
Having a separate account for system things is a useful distinction
that he can grasp and handle easily. Beyond that he is indeed inclined
to do everything as root, because what he wants is to make a turnkey to
feed his gold fish.

So a separate root account is the best protection for a single user
system. For quite a considerable part of the systems around,
sudo is over the top and stimulates no protection at all, i.e.
what I'd call counter productive.

I can save a 4-years olds life by imprinting on him to
stay on the side walk.

I can't remember ever having a need for that. I sometimes use sudo but
most times su is the way.

An administrator doesn't need the users' passwords for anything but
should be assumed to know them.

In the era of personal computers, the main advantage of the root account
is that you can breathe more easily as an ordinary user, as the
potential for accidental damage is lower.
