For the benefit of any newbies/lurkers I'll just point out that this 
might well be valid Java, but...

...this gives you class attributes, so the age is always 21 and the name 
is always 'Cool Dude'.  So you can vary the age and name you'd need:-

class person():
     def __init__(self, age, name):
         self.age = age
         self.name = name

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.
