学校选拔篮球队员，每间宿舍最多有 4 个人。现给出宿舍列表，请找出每个宿舍最高的同学。定义一个学生类 Student，有身高 height，体重 weight 等。

可以使用字典来存储每个宿舍的学生信息，然后遍历字典找出每个宿舍最高的同学。

示例代码如下：

class Student:
    def __init__(self, height, weight):
        self.height = height
        self.weight = weight

student_list = [
    Student(170, 60),
    Student(175, 65),
    Student(180, 70),
    Student(165, 55),
    Student(172, 62),
    Student(185, 75),
    Student(168, 58),
    Student(178, 68),
]

dormitory_dict = {
    "A": [],
    "B": [],
    "C": [],
    "D": [],
}

# 将学生随机分配到宿舍
import random
for student in student_list:
    dormitory = random.choice(["A", "B", "C", "D"])
    if len(dormitory_dict[dormitory]) < 4:
        dormitory_dict[dormitory].append(student)

# 找出每个宿舍最高的同学
for dormitory, students in dormitory_dict.items():
    if len(students) > 0:
        tallest_student = max(students, key=lambda s: s.height)
        print(f"The tallest student in dormitory {dormitory} is {tallest_student.height}cm tall.")
    else:
        print(f"There is no student in dormitory {dormitory}.")

输出结果类似于：

The tallest student in dormitory A is 170cm tall.
The tallest student in dormitory B is 178cm tall.
The tallest student in dormitory C is 180cm tall.
The tallest student in dormitory D is 185cm tall.
