# to define the __init__ method of the person class, you can accept any keyword argument in addition to the name, gender, and birth, and assign them all as attributes to the instance:

class Person (object):

Count = 0 #定义类属性
def __init__ (self, name, gender, birth, **kw):
Self.name = Name
Self.gender = Gender
Self.birth = Birth
For K, V in Kw.iteritems ():
SetAttr (self, k, V)

Person.count + = 1
