JSON對象中的項目是否使用“json.ddump”出現(xiàn)故障？我在用json.dumps轉(zhuǎn)換成jsoncountries.append({"id":row.id,"name":row.name,"timezone":row.timezone})print json.dumps(countries)我的結(jié)果是：[
{"timezone": 4, "id": 1, "name": "Mauritius"},
{"timezone": 2, "id": 2, "name": "France"},
{"timezone": 1, "id": 3, "name": "England"},
{"timezone": -4, "id": 4, "name": "USA"}]我希望按以下順序設(shè)置鍵：ID、Name、Timezone-但我有時區(qū)、id、name。我該怎么解決這個問題？
