python - Stopping a class variable from re-initializing when called again? -

so here example code

class hi(object)     def __init__(self):          self.answer = 'hi'      def change(self):          self.answer ='bye'         print self.answer      def printer(self):          print self.answer  class goodbye(object):      def bye(self):          hi().change()   goodbye().bye() hi().printer() 

when run code output

'bye' 'hi' 

i want output

'bye' 'bye' 

is there way while still initializing self.answer hi or cause re-initialize 'hi' no matter afterwards?

you using instance attributes not class attributes jonrsharpe pointed out.

try this:

class hi(object):     answer = 'hi'      def __init__(self):         pass      @classmethod     def change(cls):         cls.answer ='bye'         print cls.answer      def printer(self):         print self.answer  class goodbye(object):      def bye(self):         hi.change()   goodbye().bye() hi().printer() 

here answer class attribute , change() classmethod
