Python runtimeerror:thread.__init__ () not called workaround

Call an error when writing a multithreaded class
RUNTIMEERROR:THREAD.__INIT__ () not called

The code is as follows:

Class Notifytread (threading. Thread):
def __init__ (self, params):
Threading. Thread.__init__ (self) #here ...
Self.params = params

def run (self):
Print "Start notify ......"
Time.sleep (10)
Print Notify_tran (self.params)
Print "End notify ........"

Initialize the thread in init and then assign a value to the parameter to resolve it.
That is, not missing.
Threading. Thread.__init__ (self)
This is a place to use attention.
