You could do it but it would be easier to change it a little 
because the original games prompts etc betray its internal 
structure. You can just get the objects to return their attributes 
and use string formatting to insert those in your prompts. 
But it might be better to have the objercts return the whole string 
including values. Of course you can do that easily with 
a default parameter in a method:

class Explorer(object):
    fmtStr = """
My name is %s
and I have wealth of $%s and 
strength of %s"""

    # other code here    

    def describe(withText=False)
         values = (self.name, self.wealth, self.strenth)
         if not withText:
              return values
         else
              return fmtStr % values

We can then call that as

e = Explorer()
....
e.describe(withText=True)   # gets the long version

or

print """
You are an explorer whose name is %s, 
You have wealth of %s and strength of %s
""" % e.describe()  # uses tuple result

Using this technique you could use exactly the same text as 
in the original or create a more OO variant where the objects 
all know how to describe themselves.
