Timer hangs when quitting app

[Gitte Wange]

Hello,

I'm trying to create an application that needs a Timer() to do various
checks.
My class has a self.timer = Timer(900, self.sendDNSReq uest)
The timer itself works fine but whenever I try to exit the application, it
simply hangs and I have to kill the proces using `kill pid`

I have tried uncommenting the timer stuff, and then the app works as
expected.

Is there anything I need to do to kill the timer?
I have tried to create a __del__(self) function in my app. It gets called
when I leave out the timer, but with the timer enabled, it never gets
called.

Any hint will be appreciated :-)

Greetings,
Gitte Wange

A Timer is a subclass of threading.Threa d, which means
you can do "self.timer.set Daemon(True)" on it *before*
you start it, and it will not hang the app when it
is trying to exit.

See notes in the threading module's Thread.setDaemo n
docs for background.
