如下所示：

dic = dict()dic[’a’] = 1dic[’b’] = 2dic[’c’] = 3print(dic.items())import jsonjsons = json.dumps(dic)print(jsons)

結(jié)果：

dic is: dict_items([(’c’, 3), (’b’, 2), (’a’, 1)])jsons: {'c': 3, 'b': 2, 'a': 1}

通過使用collecions,進(jìn)行排序。collections是一個(gè)python的內(nèi)建模塊。

import collectionsdic = collections.OrderedDict()# dic = dict()dic[’a’] = 1dic[’b’] = 2dic[’c’] = 3print('dic is:',dic.items())import jsonjsons = json.dumps(dic)print('jsons:',jsons)

結(jié)果：

dic is: odict_items([(’a’, 1), (’b’, 2), (’c’, 3)])jsons: {'a': 1, 'b': 2, 'c': 3}

補(bǔ)充拓展：對(duì)JSON集合 某個(gè)鍵進(jìn)行升序/降序排列

我就廢話不多說了，直接上代碼吧

$(document).ready(function () { //對(duì)json進(jìn)行降序排序函數(shù) var colId='age' var desc = function(x,y) { return (x[colId] < y[colId]) ? 1 : -1 } //對(duì)json進(jìn)行升序排序函數(shù) var asc = function(x,y) { return (x[colId] > y[colId]) ? 1 : -1 } var arr2 = [ {name:'kitty', age:12}, {name:'sonny', age:9}, {name:'jake', age:13}, {name:'fun', age:24} ]; document.writeln('按age進(jìn)行升序排序：<br>'); arr2.sort(asc); //升序排序 document.writeln(JSON.stringify(arr2)); document.writeln('<br>按age進(jìn)行降序排序：<br>'); arr2.sort(desc); //降序排序 document.writeln(JSON.stringify(arr2)); });

以上這篇python通過對(duì)字典的排序,對(duì)json字段進(jìn)行排序的實(shí)例就是小編分享給大家的全部內(nèi)容了，希望能給大家一個(gè)參考，也希望大家多多支持好吧啦網(wǎng)。
