如何反序列化包含列表和字典(或键值)属性对象的json字符串

{
    "name": "Alice",
    "age": 30,
    "skills": ["Python", "Java", "C++"],
    "contact": {
        "email": "alice@example.com",
        "phone": "123-456-7890"
    }
}

import json

# JSON字符串
json_str = '''
{
    "name": "Alice",
    "age": 30,
    "skills": ["Python", "Java", "C++"],
    "contact": {
        "email": "alice@example.com",
        "phone": "123-456-7890"
    }
}
'''

# 反序列化
data = json.loads(json_str)

print(data)
print(type(data))  # 输出: <class 'dict'>

# 访问数据
print(data['name'])  # 输出: Alice
print(data['skills'])  # 输出: ['Python', 'Java', 'C++']
print(data['contact']['email'])  # 输出: alice@example.com

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

json_str = json_str.encode('utf-8').decode('utf-8')

if isinstance(data['age'], int):
    print("Age is an integer.")
