json到python字典covertion以随机顺序返回

Question

我使用“json.loads（）”将json数据转换为python字典，但输出与原始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.............. 

它不是顺序相同，像生JSON，在我来说，我需要这个以正确的顺序把它转换成html表格， 谢谢

Python字典无序，所以你松散了你的初始数据的顺序。 解决方法是在内置collections模块使用OrderedDict来自：

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