学生宿舍管理系统单链表实现pythno

以下是一个简单的学生宿舍管理系统单链表实现的 Python 代码：

class Node:
    def __init__(self, data=None, next=None):
        self.data = data
        self.next = next

class Student:
    def __init__(self, name, id, room):
        self.name = name
        self.id = id
        self.room = room

class Dormitory:
    def __init__(self):
        self.head = Node()

    def add_student(self, student):
        new_node = Node(student)
        current_node = self.head
        while current_node.next is not None:
            current_node = current_node.next
        current_node.next = new_node

    def remove_student(self, id):
        current_node = self.head
        while current_node.next is not None:
            if current_node.next.data.id == id:
                current_node.next = current_node.next.next
                return
            current_node = current_node.next
        print("Student with ID {} not found".format(id))

    def display_students(self):
        current_node = self.head.next
        while current_node is not None:
            print("Name: {}, ID: {}, Room: {}".format(current_node.data.name, current_node.data.id, current_node.data.room))
            current_node = current_node.next

使用示例：

dorm = Dormitory()

student1 = Student("Tom", 123, "A101")
student2 = Student("John", 456, "A102")

dorm.add_student(student1)
dorm.add_student(student2)

dorm.display_students() # Output: Name: Tom, ID: 123, Room: A101   Name: John, ID: 456, Room: A102

dorm.remove_student(123)

dorm.display_students() # Output: Name: John, ID: 456, Room: A102

在上面的示例中，我们首先创建了一个 `Dormitory` 对象，然后创建了两个 `Student` 对象并添加到宿舍管理系统中。接着我们打印出了所有的学生信息，然后删除了 ID 为 123 的学生，再次打印出了所有的学生信息。
