Newbie OOP Question & Code Snippet

[Dean Richardson P.Eng]

Hi All,
I'm a newbie just learning Python, using a couple of books to learn the
language. (Books: "Visual Quickstart Guide - Python, 2nd Ed", "Practical
Programming - An Intro to Computer Science using Python"). I'm just now
learning OOP material as presented in both books -- I'm new to this
approach -- the last formal language I learned was Fortran77 -- :o)  I am
running Python 3.2.1 on Mac OS/X 10.6.8.

My problem stems from a simple example in the Visual Quickstart book. The
code is:
----------------------------
#person.py
class Person:
    """Class to represent a person"""
    def __init__(self):
        self.name=' '
        self.age=0
    def display(self):
        print("Person('%s', age)" %
              (self.name, self.age))
 -------------------------
 When I run this, the shell presents thus:
>>> ================================ RESTART
================================
>>>
>>> p=Person()
>>> p.name='Bob'
>>> p.age=24
>>> p.display()
Traceback (most recent call last):
  File "<pyshell#33>", line 1, in <module>
    p.display()
  File "/Volumes/dean_richardson/GoFlex Home Personal/Dean's
Code/Python3.x/Person.py", line 9, in display
    (self.name, self.age))
TypeError: not all arguments converted during string formatting
>>>
---------------
I'm sure this is something simple, but I can't see it. Any help appreciated!

Regards,
Dean
