Cleanly exiting multi thread application on SIGINT

Is the following the most elegant way to exit a multi-threaded
application on a Ctrl-C? I am a complete beginner and would have
thought there was some way of doing it without having to use while 1:
pass, but have yet to find a way.

N.B. exit() is a method for cleanly exiting the thread using a queue.

Many thanks


def main:
wt = workerThread()
wt.setDaemon(Tr ue)
ct = counterThread()
ct.setDaemon(Tr ue)
while 1:

while 1:
you could at least insert a time.sleep(1), to avoid busy-looping.

I thought there was some sort of wait() method in the threading module, but
I was mistaken. Maybe:

while threading.activ eCount():
time.sleep(0.01 )

Hi I am developing a Dot net application (involving image processing) on a uni processor. It works well on my machine.

Hello everyone. I'm creating a simple bingo game. After the board is drawn on the screen, I try to get input from the user. If they enter an 'm', the application marks the random letter and number on the bingo board. If they type 'b', the application checks for bingo... you get the point. Now, if no input is received within x seconds, I would like to go on with the rest of my application (drawing another letter and number, printing the...

There can be, and are typically, several instances of the console app running at the same time communicating back to the service. The console app creates a delegate to do some work while the main thread waits on a ManualResetEvent to...

Hi all, I'm putting together a simple help module for my applications, using html files stored in the application directory somewhere. Basically it sets up a basic web server, and then uses the webbrowser module to display it in the users browser. I have it set up to call sys.exit(0) if the url quit.html is called, but for some reason (on Windows XP via the cmd.exe shell) python won't let me have the console back. I get the System Exit...

Hi All, I think I'm missing a basic bit of understanding with modal forms. This is the problem I have: 1. User clicks button on form, event handler throws an exception. 2. In catch block a form is shown modally (i.e. errForm.ShowDialog ()). 3. When the user closes the dialog the form image stays on the screen and the app stops painting.
