Print all variables in a class? – Python

I’m making a program that can access data stored inside a class. So for example I have this class:

#!/usr/bin/env python
import shelve

cur_dir = '.'

class Person:
    def __init__(self, name, score, age=None, yrclass=10):
        self.name = name
        self.firstname = name.split()[0]
        try:
            self.lastname = name.split()[1]
        except:
            self.lastname = None

        self.score = score
        self.age = age
        self.yrclass = yrclass
    def yrup(self):
        self.age += 1
        self.yrclass += 1

if __name__ == "__main__":
    db = shelve.open('people.dat')
    db['han'] = Person('Han Solo', 100, 37)
    db['luke'] = Person('Luke Skywalker', 83, 26)
    db['chewbacca'] = Person('Chewbacca', 100, 90901)

So using this I can call out a single variable like:

print db['luke'].name

But if I wanted to print all variables, I’m a little lost.

If I run:

f = db['han']
dir(f)

I get:

['__doc__', '__init__', '__module__', 'age', 'firstname', 'lastname', 'name', 'score', 'yrclass', 'yrup']

But I want to be able to print the actual data of those.

How can I do this?

Thanks in advance!

print db['han'].__dict__
