使用python数据类时的TypeError

from dataclasses import dataclass

@dataclass
class Person:
    name: str
    age: int

# 创建一个Person实例
person = Person(name="John", age=25)
print(person)  # 输出: Person(name='John', age=25)

# 错误示例1: 属性类型不正确
person = Person(name="John", age="25")  # TypeError: 'age' must be 'int' not 'str'

# 错误示例2: 属性缺失
person = Person(name="John")  # TypeError: missing required positional argument: 'age'

# 错误示例3: 数据类定义错误
@dataclass
class Person:
    name: str
    age  # 缺少属性类型注解
person = Person(name="John", age=25)  # TypeError: field age missing from Person
