给定这个嵌套字典,我该如何使用for循环打印所有“ phone”值？

people = {
    'Alice': {
        'phone': '2341',
        'addr': '87 Eastlake Court'
        },

    'Beth': {
        'phone': '9102',
        'addr': '563 Hartford Drive'
        },

    'Randy': {
        'phone': '4563',
        'addr': '93 SW 43rd'
        }

解决方法:

for d in people.values():
    print d['phone']
