Because inside functions, an assignment to a simple name, like
    running = 1
refers to a local variable, unless there is a "global" statement in
which case it refers to a module-level variable:
    global running
    running = 1
(this is still not what you want)
You want to refer to Server.running, as suggested in another message:
    def run(self):
        Server.running = 1

PS The first server.running might print 0 if the first line of
Server.run hasn't executed the first statement yet, of course, but
that's another story
