Python 如何比较有序字典键？

我有下列词典

{"data":[{"shift":"day","bus_type":"ac","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"},
{"shift":"night","bus_type":"deluxe","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"}]}

我在比较日班和夜班时遇到问题？ 有没有办法比较这些变化。

抱歉，如果问题似乎不相关。

如果要成对比较相同键的值，可以使用以下方法开始：

dict1, dict2 = {"data":[{"shift":"day","bus_type":"ac","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"},
    ...: {"shift":"night","bus_type":"deluxe","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"}]}['data']

[ (k,dict1[k]==dict2[k]) for k in dict1.keys()]

Out: 
[('shift', False),
 ('bus_type', False),
 ('seat_price_for_travel_agent', True),
 ('seat_price_for_user', True),
 ('seat_price_for_foreigner', True)]

如果您确定DICT具有相同的键，则可以按如下方式成对比较：

dict1, dict2 = {"data":[{"shift":"day","bus_type":"ac","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"},
    ...: {"shift":"night","bus_type":"deluxe","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"}]}['data']

[ (k,dict1[k]==dict2[k]) for k in dict1.keys()]

Out: 
[('shift', False),
 ('bus_type', False),
 ('seat_price_for_travel_agent', True),
 ('seat_price_for_user', True),
 ('seat_price_for_foreigner', True)]

---

在字典上迭代与在列表上迭代几乎相同。您可以使用

zip（）。分别使用
.items（）
、
.keys（）
或
.values（）

dic = {
    "data":
    [{"shift":"day","bus_type":"ac","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"},
   {"shift":"night","bus_type":"deluxe","seat_price_for_travel_agent":"900","seat_price_for_user":"1000","seat_price_for_foreigner":"1100"}]
}

访问完整的词典条目：

for (day, night) in zip(dic["data"][0].items(), dic["data"][1].items()):
    print(day)
    print(night)

将为您提供：

('shift', 'day')
('shift', 'night')
('bus_type', 'ac')
('bus_type', 'deluxe')
('seat_price_for_travel_agent', '900')
('seat_price_for_travel_agent', '900')
('seat_price_for_user', '1000')
('seat_price_for_user', '1000')
('seat_price_for_foreigner', '1100')
('seat_price_for_foreigner', '1100')

我想你可以从这里开始。
请以更具体的方式定义“比较”（相同的键？相同的键和值？）
