通过从列表引入值来创建类对象

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

# 假设我们有一个列表，其中包含人的姓名和年龄
people_data = [
    ['Alice', 30],
    ['Bob', 25],
    ['Charlie', 35]
]

# 使用列表中的数据创建Person对象
people = [Person(name, age) for name, age in people_data]

# 打印创建的对象信息
for person in people:
    print(f"Name: {person.name}, Age: {person.age}")

# 假设数据中有一个错误的条目
people_data_with_error = [
    ['Alice', 30],
    ['Bob', '25'],  # 错误的数据类型
    ['Charlie', 35]
]

# 在创建对象之前进行检查
people = []
for data in people_data_with_error:
    if len(data) == 2 and isinstance(data[0], str) and isinstance(data[1], int):
        people.append(Person(data[0], data[1]))
    else:
        print(f"Invalid data: {data}")

# 假设数据中有一个缺失年龄的条目
people_data_with_missing = [
    ['Alice', 30],
    ['Bob'],  # 缺失年龄
    ['Charlie', 35]
]

# 在创建对象之前进行检查
people = []
for data in people_data_with_missing:
    if len(data) == 2:
        people.append(Person(data[0], data[1]))
    elif len(data) == 1:
        print(f"Missing age for {data[0]}")
    else:
        print(f"Invalid data: {data}")
