基于DataType如何组合"collectionResult“

class User:
    def __init__(self, id: int, name: str, email: str):
        self.id = id
        self.name = name
        self.email = email

# 假设collectionResult是从某处获取的用户信息列表
collectionResult = [
    {"id": 1, "name": "Alice", "email": "alice@example.com"},
    {"id": 2, "name": "Bob", "email": "bob@example.com"}
]

# 将collectionResult转换为User对象的列表
users = [User(item['id'], item['name'], item['email']) for item in collectionResult]

# 打印用户信息
for user in users:
    print(f"ID: {user.id}, Name: {user.name}, Email: {user.email}")

def create_user(item):
    try:
        return User(
            id=item.get('id', None),
            name=item['name'],
            email=item['email']
        )
    except KeyError as e:
        print(f"Missing key: {e}")
        return None

users = [create_user(item) for item in collectionResult if create_user(item) is not None]
