Hi All,
I'm new bie to thread programming and I need some assistance in
understanding few concepts ...
I have a very simple program which runs a thread and prints a string.
import threading
class MyThread(threading.Thread):
def __init__(self, parent = None):
threading.Thread.__init__(self)
def run(self):
print 'Hello World'
def main():
for i in range(10):
MyThread_Object = MyThread()
print 'Object id is : ' , id(MyThread_Object)
print 'Staring thread ----------> ' , MyThread_Object.getName()
MyThread_Object.start()
count = threading.activeCount()
print 'The active thread count is: ' , count
if __name__ == '__main__':
main()
When I run this, I could see 10 thread being called. But when I print the
active thread count it is only 2.
Need some understanding on the following.
1. How the total active thread is 2?
2. how do I stop a thread? does it get automatically stopped after execution
?
3. Am I totally wrong in understanding the concepts.
4. what is the difference between active_count() and activeCount() since
both seem to give the same result.
5. is there a way to find out if the thread is still active or dead?
Please help me in understanding ..
