大致流程：

导包---import collections
新建一个有序字典---collections.OrderedDict()
写入json文件

代码：

import collectionsreal_result = collections.OrderedDict()real_result["target"] = "total_result"real_result["key1"] = "value1"real_result["key2"] = "value2"real_result["key3"] = "value3"real_result_total = [real_result]print real_result_total输出：[OrderedDict([('target', 'total_result'), ('key1', 'value1'), ('key2', 'value2'), ('key3', 'value3')])]current_dir = os.path.dirname(os.path.realpath(__file__))path = os.path.join(os.path.join(current_dir, 'jsonfile'), result_json)with open(path, 'w') as f:  json.dump(real_result_total, f, encoding="utf-8", ensure_ascii=False, indent=4, separators=(',', ':'))
