python - Understanding inheritance in practice. Printing values of an instance -


i have class of agents working __str__ method. have class of family(agents). family structured dictionary agent id key. after allocating agents families, iterate on my_families: when print members.keys(), correct keys. when print members.values(), list of instances

but, cannot access values inside instances. when try use method get_money() answer family class not have method. help?

for family in my_families:     print family.members.values() 

thanks

providing more information. family class

class family(agents.agent): """ class set of agents """     def __init__(self, family_id):         self.family_id = family_id         # _members stores agent set members in dictionary keyed id         self.members = {}      def add_agent(self, agent):         "adds new agent set."         self.members[agent.get_id()] = agent 

class of agents

class agent():     "class agent objects."     def __init__(self, id, qualification, money):         # self._id unique id number used track each person agent.         self.id = id         self.qualification = qualification         self.money = money      def get_id(self):         return self.id      def get_qual(self):         return self.qualification      def get_money(self):         return self.money      def __str__(self):     return 'agent id: %d, agent balance: %d.2, years of study: %d ' (self.id, self.money, self.qualification)  #allocating agents families  def allocate_to_family(agents, families):     dummy_agent_index = len(agents)     family in families:         dummy_family_size = random.randrange(1, 5)         store = dummy_family_size         while dummy_family_size > 0 , dummy_agent_index >= 0 , (dummy_agent_index - dummy_family_size) > 0:             family.add_agent(agents[dummy_agent_index - dummy_family_size])             dummy_family_size -= 1         dummy_agent_index -= store 

finally printing example gets me instance objects not values

for family in my_families:     print family.members.values() 

if family supposed contain agent objects, why inherit agent? regardless, never initialized parent agent object in family class's __init__, , according edit get_money method contained in agent class, family objects don't have get_money method. access that, need first access family object's members dictionary, use key access desired agent object, access object's get_money method.
