It is not a double use. Popen(["z6.py"], stdout=PIPE) gives you a Popen
object, not a file object. If you add .stdout you get the stdout
attribute of the Popen object of which you just before stated that it
should be a pipe. So the stdout=PIPE parameter makes it create a pipe,
and the .stdout returns you that pipe.
I rather thought it might be something like the military:
Company - Dress Right - Dress
Get the attention, state what is to be done, order it done. :)
Python goes to great lengths to "be helpful" but drops the ball on the
obvious. stdout=PIPE means the user wants stdout piped back so it
should be helpful and do the obvious rather than have the user be
redundant.
What if the user requests both stdin and stdout? and what about all the
other useful bits which the returned object provides?
