本节例题中**kw多了两个新参数，**kw或者*args 怎么添加多于两个的新参数
class Person(object):
def __init__(self, name, gender, **kw):
self.name = name
self.gender = gender
for k, v,x ,z in kw.iteritems():
setattr(self,k ,v, x ,z)
p = Person('Bob', 'Male', age=18, course='Python', score=88)
print p.name
print p.age
print p.course
print p.score
