how to drop all thread ??

By exiting. There is no other way to stop a thread by force. Of course you
can write a run()-method like this:
def run(self):
while self.running_condition:
# do something
pass

If that running-condition is queried often enough, you can stop the thread
by setting it to false.

Note that even trying to exit won't work, if the threads are not
marked as "daemon" threads... Only by calling .setDaemon(True) on
the threads before they are started will you be able to terminate
them all just by exiting.

This reply is off topic but I couldn't resist:

The best way to get rid of thread is to adopt a kitten.

In fact, one of my cats is named Snobol because she is such a good string
manipulator.

Hi !

The best method, it is the suicide (of the threads).

As Roggisch suggests, the cleanest way is if the thread kills itself
once signaled by an exit condition. However, there is a non-orthodox way
of pseudo-forcibly killing threads by catching the kill signal in a
traceback. This method is summed up in Connelly Barnes's informal
KThread module:

Note it won't work in all cases, as it can't kill a thread that's made a
blocking system call. However, it may come in useful.
