否，但是您可以将dict归类为更改通知。
class ObservableDict( dict ): def __init__( self, *args, **kw ): self.observers= [] super( ObservableDict, self ).__init__( *args, **kw ) def observe( self, observer ): self.observers.append( observer ) def __setitem__( self, key, value ): for o in self.observers: o.notify( self, key, self[key], value ) super( ObservableDict, self ).__setitem__( key, value ) def update( self, anotherDict ): for k in anotherDict: self[k]= anotherDict[k]class Watcher( object ): def notify( self, observable, key, old, new ): print "Change to ", observable, "at", keyw= Watcher()a= ObservableDict( {'a':'hamburger', 'b':'fries', 'c':'coke'} )a.observe( w )b = {'b':'fries', 'c':'pepsi'}a.update( b )请注意，此处定义的超类监视程序不会检查是否存在“真实”更改；它只是指出发生了变化。
