如何有效地总结python中对象列表的属性？

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

# 创建一个Person对象列表
people = [
    Person('Alice', 30),
    Person('Bob', 25),
    Person('Charlie', 35)
]

# 使用列表推导式获取所有人的年龄
ages = [person.age for person in people]
print(f"所有人的年龄: {ages}")

# 使用内置函数进行统计总结
total_age = sum(ages)
average_age = total_age / len(ages)
max_age = max(ages)
min_age = min(ages)

print(f"总年龄: {total_age}")
print(f"平均年龄: {average_age}")
print(f"最大年龄: {max_age}")
print(f"最小年龄: {min_age}")

# 如果想要按年龄段分组，可以使用字典
from collections import defaultdict

age_groups = defaultdict(list)
for person in people:
    age_groups[person.age // 10 * 10].append(person.name)

print("按年龄段分组:")
for age, names in age_groups.items():
    print(f"{age}-{age+9}岁: {', '.join(names)}")
