Need help in program not losing information

[biganimal]

This is a repost coded for everyone to read a little easier. I created this program for my daughter to use but I want the program to retain information on questions/answers and not have to start over every time program is started.

# questor.py
 
 # define some constants for futureuse
 
kQuestion = 'question'
kGuess = 'guess'
 
# define a function for asking yes/no questions
def yesno(prompt): 
          ans = raw_input(prompt) 
          return (ans[0]=='y' or ans[0]=='Y')
 
# define a node in the question tree (either question or guess)
class Qnode: 
 
          # initialization method 
          def __init__(self,guess): 
                     self.nodetype = kGuess 
                     self.desc = guess 
          # get the question to ask 
          def query(self): 
                     if (self.nodetype == kQuestion): 
                               return self.desc + " " 
                     elif (self.nodetype == kGuess): 
                        return "Is it a " + self.desc + "? " 
                     else: 
                        return "Error: invalid node type!" 
 
          # return new node, given a boolean response 
          def nextnode(self,answer): 
                     return self.nodes[answer] 
  
          # turn a guess node into a question node and add new item 
       # give a question, the new item, and the answer for that item   
          def makeQuest( self, question, newitem, newanswer ): 
 
       # create new nodes for the new answer and old answer newAnsNode = Qnode(newitem)

           if (fromNode.nodetype == kGuess):
                      if (yes): 
                         print "I'm a genius!!!" 
                         return 
           # if we didn't get it right, return the node 
           return fromNode

           return traverse( fromNode.nextnode(yes) )
