如何在python中创建一个多维字典/对象

Question

我有这个对象：

"products":[
   {
      "title":"ASUS ZenFone 4 Max",
      "author":"1",

            "camera":5,

      },
      "terms":{
         "aps-cats":[
            "smartphones"
         ]
      }
   },...]

我需要在循环中动态实现这一点。例如：

#Initial declaration
products = {"products":{}}

#Add items in the products object
products["title"] = "ASUS ZenFone 4 Max"
products["author"] = "1"

for items in product_list:
    products["meta"]["post_views_count"] = 0
    products["meta"]["aps-product-sku"] = "SKU"

我似乎无法弄清楚如何添加下一个也有“title”，“author”，“meta”的产品（这也是一个具有键值对的对象）等。

我希望你能理解我的疑问。我正在做网络抓取:)

谢谢

Answer 1

试试这样：

products = []
product1 = {}
product1["title"] = "ASUS ZenFone 4 Max"

product2 = {}
product2["title"] = "Galaxy S8"

products.append(product1)
products.append(product2)

print(products)

Answer 2

if __name__ == '__main__':

new_list = list()
new_product_dict = {
  "title":"new title",
  "author":"new author",
  "date":"2017-12-18 21:49:30",
  "date_gmt":"0000-00-00 00:00:00",
  "content":"",
  "status":"draft",
  "comment_status":"open",
  "image":""}

for items in product_list.values():
    new_list = [new_product_dict]
    items.append(new_list)
print(items)

这种方法对我有用，当然你可以在for循环中添加更多的dicts
