Python/JSON在字典中获取值，当您从嵌套字典中获得键时？

import json

# 假设有一个嵌套字典的JSON数据
json_data = '''
{
  "person": {
    "name": "John",
    "age": 30,
    "address": {
      "street": "123 Street",
      "city": "New York"
    }
  }
}
'''

# 将JSON数据转换为Python字典
data = json.loads(json_data)

# 通过键来获取值
name = data["person"]["name"]
age = data["person"]["age"]
street = data["person"]["address"]["street"]
city = data["person"]["address"]["city"]

# 打印获取到的值
print("Name:", name)
print("Age:", age)
print("Street:", street)
print("City:", city)

Name: John
Age: 30
Street: 123 Street
City: New York
