关于迭代器的问题？

将一个dict通过iter()转化成迭代器类型，发现只能度取出key值，无法读取里面的value 或者item了，因为迭代器不支持.values()与.items()格式，那该如何提取key值和item呢

明明都可以啊 values(), items()

来利强

#3 Created at ... [Delete] [Delete and Lock User] 
d = {"name": "张三", "age": "666"}
it = iter(d.items())
while 1:
    try:
        v = next(it)
        print v
    except StopIteration as e:
        break

取values 

it = iter(d.values())
