Python 如何将嵌套的JSON值返回到字典？

我正在使用scrapy从seek.com.au上获取评论。我已经找到了这个链接，其中包含我需要用JSON编码的数据

数据如下所示：

{ 
   "paging":{ 
      "page":1,
      "perPage":20,
      "total":825
   },
   "data":[

         "cons":"Sell, sell, sell! Everything at CBA is about selling. Don't believe the reports that  things have changed and performance is based on customer service. They may have on paper but sales numbers are still tracked.",

      },

我创建了一个字典，然后尝试返回数据，但只返回1个值

    name = 'seek-spider'
    allowed_domains = ['seek.com.au']
    start_urls = [
        'https://www.seek.com.au/companies/commonwealth-bank-of-australia-432306/reviews']
    s = str(start_urls)
    res = re.findall(r'\d+', s)
    res = str(res)
    string = (res[res.find("[")+1:res.find("]")])
    string_replaced = string.replace("'", "")
    start_urls = [
        'https://company-profiles-api.cloud.seek.com.au/v1/companies/'+string_replaced+'/reviews?page=1']

    def parse(self, response):
        result = json.loads(response.body)
        detail = {}
        for i in result['data']:
            detail['ID'] = i['id']
            detail['Title'] = i['title']
            detail['Pros'] = i['pros']
            detail['Cons'] = i['cons']
        return detail

我希望输出包含所有数据，但只返回以下数据：

{'ID': 135413, 'Title': 'Great place to work!', 'Pros': 'All of the above.', 'Cons': 'None that I can think of'}

我正在创建的词典正在删除我以前的数据。我在循环之前创建了一个列表，问题就解决了

    def parse(self, response):
        result = json.loads(response.body)
        res = []
        for i in result['data']:
            detail = {}
            detail['id'] = i['id']
            res.append(detail)
        return res
