stdout and threads


Hello All

I have trouble printing to stdout from a thread and main program.

Not only will it look strange when they try to print at the same time, that
is ok, but i think i see lock-ups. (strange exceptions in Tkinker etc) Or is
it an issue with IDLE ?

Should I implement a lock'ed / queued version and hook it into the
sys.stdout ?

(sorry if this has been answered recently in this group)

using
Python 2.5 (r25:51908
Idle 1.2

I've read in multiple sites/books that running Tkinter from IDLE can
cause screwy errors and I've seen a little bit of that behavior
myself. This website mentions the problem: http://www.ferg.org/thinking_in_tkinter/index.html

using the Queue module for messages is a good way to go, using
producer and consumer threads. Then just check the queue from time to
time to grab the messages and print them out, maybe to a separate
text widget.
