对象继承和嵌套cmd

您不需要多重继承，但是需要为继承的对象赋予obj1和obj2，除非您为obj1和obj2提供一些默认值。

class SubConsole1(MainConsole):    def __init__(self, obb1, obj2):        MainConsole.__init__(self, obj1, obj2)        self.prompt = "1>"    def do_action(self,args):        print self.obj1.someattr1 # Doesn't work

实例化：

sub1 = SubConsole1(object1, object2)
