Solve the following python programming problem given the following code:
def __init__(self, scheduler, messages) : 
    log.debug ('HotObservable.__init__()') 
    Observable.__init__ (self, self._subscribe) 
    self.scheduler = scheduler 
    self.messages = action 
    self.subscriptions = AssertList () 
    self.observers = [] 
    observable = self 
    def get_action(notification) : 
        def action(scheduler, state) : 
            for observer in observable.observers [:] : 
                notification.accept (observer) 
return Disposable.empty () 
return action 
for message in self.messages : 
        notification = message.value 
        action = get_action (notification) 
        scheduler.schedule_absolute (message.time, action) 

    
    

    Fix the buggy line: self.messages = action

#Here is Python program to fix the buggy line: self.

self.messages = messages
