 it cannot.  threads cannot be killed from the outside.

The only way to kill a thread is to have the spawned thread have
some kind of passed in argument which will trigger it to shut down.
You could have the thread read a file or file-like object periodically
(like a timer) and if it meets some condition, have the thread quit.

It's kind of like a subscription process. The thread subscribes to the
main program and can accept signals. I suggest that the OP read the
docs on threads:

http://docs.python.org/lib/module-threading.html

Of special interest to this user: 
http://docs.python.org/lib/condition-objects.html

I have messed with KillProcName, a PyWin32 script with limited
success. There's also the following snippet which is Windows only and
works for some processes and not others (i.e. unreliable):

subprocess.Popen('taskkill /s %s /im %s' % (computer_id, proc))

Hopefully I didn't muddy the waters or write something too off the
mark.

Hello All,

Can anyone help me with a simple code through which the main thread can kill
the worker thread it started.

Thanks  Regards,

You can use the stop method!

You can?

  import threading
  t = threading.Thread()
  t.stop()
Traceback (most recent call last):
   File stdin, line 1, in module
AttributeError: 'Thread' object has no attribute 'stop'
 

What Python version are you using?
