我从API获取以下数据.我试图使用Python脚本访问餐厅名称并让脚本显示它.这是我的文件:

test.py

with open('data.json') as data_file:    
    data = json.load(data_file)
    for restaurant in data:
        print data ['restaurants'][0]['restaurant']['name']

我的JSON文件如下:(简化)

  "results_start": 0,
  "results_shown": 20,
  "restaurants": [
    {

        "R": {
          "res_id": 9101083
        },

我只想通过 id 获取用户，如果他们没有deleted=0. 我试过

user = User.query.filter_by(deleted=0).get(id)

但出现错误。如何过滤查询并通过 id 获取？
