Python嵌套的jSon对象

Question

我正在尝试将我的对象嵌套到另一个称为“图形卡”的对象中，但是我很难弄清楚它。 我已经尝试了几件事，但是没有得到想要的输出。

[
  {
    "Graphics Card":
      {
        "Brands": "Brand Name",  
        "Products": "Product Name",
        "Shipping": "Brand Name"
      }
  }
]

下面是我的代码。 任何帮助表示赞赏。 谢谢！

from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup
import json 

my_url = 'https://www.newegg.com/Video-Cards-Video-Devices/Category/ID-38?Tpk=graphics%20cards'

# opening up connection, grabbing the page
uClient = uReq(my_url)
page_html = uClient.read()
uClient.close()

# html parsing
page_soup = soup(page_html, "html.parser")

# grabs each product
containers = page_soup.findAll("div", {"class":"item-container"})


items = []


for container in containers: 
    brand = container.div.div.a.img["title"]

    title_container = container.findAll("a",{"class":"item-title"})
    product_name = title_container[0].text

    shipping_container = container.findAll("li", {"class":"price-ship"})
    shipping = shipping_container[0].text.strip()

    items.append({"Brands": brand, "Products": product_name, "Shipping": shipping })

print(json.dumps(items, sort_keys=True, indent=4))

fout = open("text.json", 'w')
json.dump(items, fout, sort_keys=True, indent=4)
fout.close()

您问题中的JSON确实没有任何意义。

一个人会期望

{ "graphics cards": [ {object1}, {object2},... ] }

也许是这样，但是您丢失了数据中的关联值...所以可能不会

{ "graphics cards": { "brands": [ ... ], "products": [...], "shipping": [...] }

话虽如此，您想这样做。

final_items = { "Graphics Cards": items }
print(json.dumps(final_items, sort_keys=True, indent=4))

而且您的代码工作正常。

{
    "Graphics Cards": [
        {
            "Brands": "GIGABYTE",
            "Products": "GIGABYTE GeForce GTX 1060 Windforce OC GV-N1060WF2OC-6GD Video Card",
            "Shipping": "Free Shipping"
        },
        {
            "Brands": "XFX",
            "Products": "XFX Radeon GTR RX 480 DirectX 12 RX-480P8DBA6 Black Edition Video Card",
            "Shipping": "$4.99 Shipping"
        },

建议，尽管对于“更好的” JSON数据：将每个“品牌”分组在一起。

{ 
    "cards": [
        "GIGABYTE": [
            { 
                "Products": "GIGABYTE GeForce GTX 1060 Windforce OC GV-N1060WF2OC-6GD Video Card",
                "Shipping": "Free Shipping"
            }, 
            { 
                "Products": "GIGABYTE GeForce GTX 1050 Ti DirectX 12 GV-N105TWF2OC-4GD Video Card",
                "Shipping": "Free Shipping"
            }
        ], 
        "XFX": [ ... ]
    ]
}
