从嵌套的Json中提取参数

import json

# 假设有一个嵌套的Json字符串
json_str = '''
{
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "country": "USA"
  }
}
'''

# 将Json字符串解析为字典对象
data = json.loads(json_str)

# 提取参数值
name = data["name"]
age = data["age"]
street = data["address"]["street"]
city = data["address"]["city"]
country = data["address"]["country"]

# 打印提取的参数值
print("Name:", name)
print("Age:", age)
print("Street:", street)
print("City:", city)
print("Country:", country)

Name: John
