Python：对于defaultdict，打印键和值


Python: For defaultdict, print keys and values

本问题已经有最佳答案，请猛点这里访问。

这本词典不断地用键和值来变化。所以，我想访问这些键和值，并像预期的答案一样打印出来。因为我对python还不熟悉，所以任何帮助都会非常感谢。

     dictionary=
       {'key1': {'key10': [[66619, 'event1'], [64800, 'event2']]},
        'key2': {'key11': [[28250, 'event3'], [17960, 'event4'], [23484, 'event5'], [21945, 'event6']]},
        'key3': {'key12': [[359319, 'event7'], [322334, 'event8'], [273316, 'event9']], 'key13': [[452945, 'event10'], [414268, 'event11']]}
       }

预期答案：

姓名：key1，地址：key10，号码：66619，密码：event1

姓名：key1，地址：key10，号码：64800，密码：event2

姓名：key2，地址：key11，号码：28250，密码：event3

姓名：key2，地址：key11，号码：17960，密码：event4

姓名：key2，地址：key11，号码：23484，密码：event5

姓名：key2，地址：key11，号码：21945，密码：event6

姓名：key3，地址：key12，号码：359319，密码：event7

姓名：key3，地址：key12，号码：322334，密码：event8

姓名：key3，地址：key12，号码：273316，密码：event9

姓名：key3，地址：key13，号码：452945，密码：event10

姓名：key3，地址：key13，号码：414268，密码：event11

这本词典本质上是无序的。如果你想在dict内维持订单，就必须使用collections.OrderedDict()。根据OrderedDict号文件：

Return an instance of a dict subclass, supporting the usual dict
methods. An OrderedDict is a dict that remembers the order that keys
were first inserted. If a new entry overwrites an existing entry, the
original insertion position is left unchanged. Deleting an entry and
reinserting it will move it to the end.

如果您只想打印此内容而不实际存储已排序的数据，可以使用简单的sorted()功能进行打印，如下所示：

from operator import itemgetter

for k, v in sorted(dictionary.items(), key=itemgetter(0)):
    for k1, v1 in sorted(v.items(), key=itemgetter(0)):
        for content in v1:
            print 'Name: {}, Address: {}, Number: {}, Pin: {}'.format(k, k1, content[0], content[1])

将打印：
