Python Programming Language :: stdout and threads


	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 ?

This website mentions the problem: http://www.ferg.org/thinking_in_tkinter/index.html >From what I've read in Lutz's book, Programming Python, it sounds like 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. Mike
