Class definition

class Person(object): 
 def __init__(self, name, age): 
      self.name = name 
      self.age = age 
 def birthday(self): 
      self.age += 1

Note class name is capitalized. Initialization is the constructors where self.xyz defines class variables. Next def defines a function. Class functions take self as the default, 1st parameter.
