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.
