if __name__ == '__main__': rospy.init_node('distance_node') soundPub = rospy.Publisher('/distance', Range, queue_size=1) pub_range = Range() try: while True:
Well, this is an endless loop. That is why it won't shut down.
You'll want to check for an exit condition and break the loop.
A good exit condition when using rospy
would be to see whether ROS has been requested to shutdown, so something like this would work:
while not rospy.is_shutdown():
For reference, see the Writing a Simple Publisher and Subscriber (Python) tutorial on the wiki.
