【问题描述】：

我正在使用“json.loads()”将 json 数据转换为 python 字典，但输出的顺序与原始 json 数据的顺序不同。

json

{
"cam":{
"cam1":{"dly":11,"val":12,"alg":13,"blk":14},
"cam2":{"dly":21,"val":22,"alg":23,"blk":24},
"cam3":{"dly":31,"val":32,"alg":33,"blk":34},
"cam4":{"dly":41,"val":42,"alg":43,"blk":44},
"cam5":{"dly":51,"val":52,"alg":53,"blk":54},
"cam6":{"dly":61,"val":62,"alg":63,"blk":64},
"cam7":{"dly":71,"val":72,"alg":73,"blk":74},
"cam8":{"dly":81,"val":82,"alg":83,"blk":84},
"cam9":{"dly":91,"val":92,"alg":93,"blk":94},
"cam10":{"dly":101,"val":102,"alg":103,"blk":104},
"cam11":{"dly":111,"val":112,"alg":113,"blk":114},
"cam12":{"dly":121,"val":122,"alg":123,"blk":124},
"cam13":{"dly":131,"val":132,"alg":133,"blk":134},
"cam14":{"dly":141,"val":142,"alg":143,"blk":144}
}
}

python2_7.py

import json

jscam=json.loads(json)  #printing this also shows datas are unorderd
cam_js=jscam['cam']

for key,value in cam_js.iteritems():
    print key
    for key1,value1 in value.iteritems():
       print key1,value1
       print('\n')

输出

cam9
val 92
alg 93
blk 94
fl 91


cam8
val 82
alg 83
blk 84
fl 81

cam3
val 32
alg 33
blk 34
fl 31..............

它的顺序与原始 json 不同，在我的情况下，我需要以正确的顺序将其转换为 html 表，谢谢

【解决方案1】：

Python dict 是无序的，因此您会失去初始数据的顺序。解决方法是使用内置collections 模块中的OrderedDict：

import json
import collections
ordered_json = json.loads(your_json_string, object_pairs_hook=collections.OrderedDict)
