declaimed the following in gmane.comp.python.general:
Since I'm using threads and pipes everything works ok, except that when i call
input() there is no way that I could print something, is there any workaround
for this??
Note: I don't need to catch any key's before enter or smtng, just be able to
print while input() is waiting. I'm thinking that maybe there is a way for two
threads to share one stdout, which should resolve this, but I can't make it
work, since U can't pickle file like object(stdout) to pass it to other thread.
Confusion abounds...
You don't have to "pickle file like object..." for it to be used by
a Python THREAD... But your mention of pipes makes me think you are
using subprocesses and/or multiprocessing modules. Threads run in a
shared environment (you may need to put a lock around the file object so
that only one thread at a time does the I/O on that object), but
processes are independent memory spaces.
However, you may also encounter OS specific behavior WRT
stdout/stderr when they are connected to a console. The OS itself may
block/buffer output when there is a pending input on the same console.

You can clear the buffer by calling file.flush()
Shock, horror, probe, well I never did. I'm sure that everyone is
updating their Xmas and birthday card lists to ensure that you're not
missed out having furnished a piece of information that doubtless not
one other person on this group knew.
