如下所示：
dic = dict() dic['a'] = 1 dic['b'] = 2 dic['c'] = 3 print(dic.items()) import json jsons = json.dumps(dic) print(jsons)
结果：
dic is: dict_items([('c', 3), ('b', 2), ('a', 1)])
jsons: {"c": 3, "b": 2, "a": 1}
通过使用collecions,进行排序。collections是一个python的内建模块。
import collections
dic = collections.OrderedDict()
# dic = dict()
dic['a'] = 1
dic['b'] = 2
dic['c'] = 3
print("dic is:",dic.items())
import json
jsons = json.dumps(dic)
print("jsons:",jsons)
结果：
dic is: odict_items([('a', 1), ('b', 2), ('c', 3)])
jsons: {"a": 1, "b": 2, "c": 3}
补充拓展：对JSON集合 某个键进行升序/降序排列
我就废话不多说了，直接上代码吧
$(document).ready(function () {
//对json进行降序排序函数
var colId="age"
var desc = function(x,y)
{
return (x[colId] < y[colId]) "kitty", age:12},
{name:"sonny", age:9},
{name:"jake", age:13},
{name:"fun", age:24}
];
document.writeln("按age进行升序排序：<br>");
arr2.sort(asc); //升序排序
document.writeln(JSON.stringify(arr2));
document.writeln("<br>按age进行降序排序：<br>");
arr2.sort(desc); //降序排序
document.writeln(JSON.stringify(arr2));
});
以上这篇python通过对字典的排序,对json字段进行排序的实例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
