Python循环通过特定的JSON对象

{
    "name": "Alice",
    "age": 30,
    "hobbies": ["reading", "traveling"]
}

import json

# JSON字符串
json_str = '{"name": "Alice", "age": 30, "hobbies": ["reading", "traveling"]}'

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

# 遍历JSON对象
for key, value in data.items():
    print(f"{key}: {value}")

# 如果需要遍历数组
for hobby in data['hobbies']:
    print(hobby)

try:
    data = json.loads(json_str)
except json.JSONDecodeError as e:
    print(f"JSON解析错误: {e}")

if 'name' in data:
    print(data['name'])
else:
    print("键 'name' 不存在")

if isinstance(data['age'], int):
    print(f"年龄: {data['age']}")
else:
    print("年龄字段不是整数类型")
