json到python字典covertion以隨機順序返回

Question

我使用「json.loads（）」將json數據轉換爲python字典，但輸出與原始json數據的順序不同。

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') 

輸出

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.............. 

它不是順序相同，像生JSON，在我來說，我需要這個以正確的順序把它轉換成html表格， 謝謝

Python字典無序，所以你鬆散了你的初始數據的順序。 解決方法是在內置collections模塊使用OrderedDict來自：

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