Question

我是python的新手，并试图从python json文档中获取数据，我尝试将信息传递给python，json从python打印带有表格样式的pdf。我在json中的代码是

[
    {
        "files": 0, 
        "data": [
            {"name": "RFC", "value": "XXXXXXX", "attId": 01}, 
            {"name": "NOMBRE", "value": "JOSE", "attId": 02}, 
            {"name": "APELLIDO PATERNO", "value": "MONTIEL", "attId": 03}, 
            {"name": "APELLIDO MATERNO", "value": "MENDOZA", "attId": 04}, 
            {"name": "FECHA NACIMIENTO", "value": "1989-02-04", "attId": 05}
        ], 
        "dirId": 1, 
        "docId": 4, 
        "structure": {
            "name": "personales", 
            "folioId": 22
        }
    }, 
    {
        "files": 0, 
        "data": [
            {"name": "CALLE", "value": "AMOR", "attId": 06}, 
            {"name": "No. EXTERIOR", "value": "4", "attId": 07}, 
            {"name": "No. INTERIOR", "value": "2", "attId": 08}, 
            {"name": "C.P.", "value": "55060", "attId": 09}, 
            {"name": "ENTIDAD", "value": "ESTADO DE MEXICO", "attId": 10}, 
            {"name": "MUNICIPIO", "value": "ECATEPEC", "attId": 11}, 
            {"name": "COLONIA", "value": "INDUSTRIAL", "attId": 12}
            ], 
        "dirId": 1, 
        "docId": 4, 
        "structure": {
            "name": "direccion", 
            "folioId": 22
        }
    }
]

并在python中提示下一个代码

import json
f= open(prueba.json)
prueba = json.load(f)
prueba

正确打印json的内容，但我的想法只是例如：

Nombre,Jose

然后使用参数以pdf格式构建表格

我试过以下

 import json
 json_data = []
 with open('prueba.json') as json_file:
     json_data = json.load(json_file)
 for key, value in json_data.iteritems():
   print key; 
   for item in value: 
      print item 
      for key, value in json_data.iteritems(): 
         print key; 
         for item in value: 
            print item

但我有下一个错误：

    AttributeError : 'list' object has no attribute 'iteritems'

我试图为他们做点什么，但我必须得到json的每个数据

Answer 1

json_data = [] # your list with json objects (dicts)

for item in json_data:
    for data_item in item['data']:
        print data_item['name'], data_item['value']

Answer 2

像

这样的东西

for key, value in json_data.iteritems():
    print key
    if isinstance(value, (list, tuple)):
        for item in value: 
            print item
    if isinstance(value, (dict)):
        for value_key,value_value in value.iteritems(): 
            print value_key,str(value_value)

可以改进以管理更多类型，并且可以递归。

如何使用python从列表Json获取数据？
