使用python在JSON中查找数据

import json

# 定义一个JSON字符串
json_str = '''
{
  "name": "John",
  "age": 30,
  "city": "New York",
  "pets": [
    {
      "name": "Max",
      "species": "dog"
    },
    {
      "name": "Lucy",
      "species": "cat"
    }
  ]
}
'''

# 将JSON字符串解析为Python对象
data = json.loads(json_str)

# 使用键来查找数据
name = data['name']
age = data['age']
city = data['city']

# 使用索引和键来查找嵌套的数据
pet_name = data['pets'][0]['name']
pet_species = data['pets'][0]['species']

# 打印结果
print("Name:", name)
print("Age:", age)
print("City:", city)
print("Pet Name:", pet_name)
print("Pet Species:", pet_species)

Name: John
Age: 30
City: New York
Pet Name: Max
Pet Species: dog
