Python（json）如何將同名的每個鍵添加到串列中-有解無憂

我需要將密鑰名稱和密鑰年齡中的每個值添加到串列中

但是在這段代碼開始后有：

for i in len(jsondata['name']): builtins.KeyError: 'name'

但是你看到我在第二個中有"name": "husky"和"name": "shiba inu"。那你會改寫什么？

謝謝

import json

names=[]
ages=[] 


#f = open('jsondata.json')

with open('jsondata.json') as fp:
    jsondata = json.load(fp)


for i in len(jsondata['name']):
    names.add(jsondata['name'])

for i in len(jsondata['age']):
    ages.add(jsondata['age'])

f.close()

json檔案：

{
    "dogs": [
        {
            "name": "husky",
            "age": "12",
            "urls": [
                "https://www.dailypaws.com/dogs-puppies/dog-names/husky-names",
                "https://www.tonbridgehuskymalamutewalkinggroup.co.uk/"
            ]
        },
        {
            "name": "shiba inu",
            "age": "3",
            "urls": [
                "https://www.cryptoglobe.com/latest/2021/10/shiba-inu-shib-listed-on-trading-app-with-over-one-million-users/",
                "https://www.purina.co.uk/find-a-pet/dog-breeds/japanese-shibu-inu"
            ]
        }
    ]
}

for dog in jsondata["dogs"]:
    names.append(dog["name"])
    ages.append(dog["age"])

uj5u.com熱心網友回復：

您需要獲取嵌套順序。如您所見，鍵 'name' 在 'dogs' 下，則鍵 'name' 在 . 因此，您需要將其稱為

for i in range(len(jsondata['dogs'])):
    names.append(jsondata['dogs'][i]['name'])

如果你想獲得條目

uj5u.com熱心網友回復：

您應該在dogs元素上應用回圈

name = []
age = []
data = """{
  "dogs": [
    {
      "name": "husky",
      "age": "12",
      "urls": [
        "https://www.dailypaws.com/dogs-puppies/dog-names/husky-names",
        "https://www.tonbridgehuskymalamutewalkinggroup.co.uk/"
      ]
    },
    {
      "name": "shiba inu",
      "age": "3",
      "urls": [
        "https://www.cryptoglobe.com/latest/2021/10/shiba-inu-shib-listed-on-trading-app-with-over-one-million-users/",
        "https://www.purina.co.uk/find-a-pet/dog-breeds/japanese-shibu-inu"
      ]
    }
  ]
}"""
    for m in data['dogs']:
        u_name= name.append(m.get('name','N/A'))
        u_age = age.append(m.get('age','N/A'))

m.get('age','N/A')陳述句將用作if-elseJSON 中的陳述句
