展开阅读网页

上述代码中,DormManagementSystem类中的dorms是一个列表,用于存储Dorm类的实例对象。1

📝 列表定义

  • 列表类型dorms 是一个 Python 列表,用于存储多个 Dorm 对象。1

🔧 方法操作

  • 添加宿舍add_dorm 方法将 Dorm 对象添加到 dorms 列表中。1
  • 分配学生assign_student_to_dorm 方法通过检查 dorms 列表来确认宿舍是否存在。1

📚 示例使用

  • 创建宿舍:在示例中,通过 Dorm("A楼1号楼", 1, 6) 创建 Dorm 对象,并使用 add_dorm 方法将其添加到 dorms 列表中。1

不在提醒

上述代码中,DormManagementSystem类中的dormsDorm类的实例对象,这一规定是通过类的定义和方法的实现来实现的。具体来说,DormManagementSystem类通过其构造函数初始化了一个空列表dorms,并在其add_dorm方法中将Dorm类的实例对象添加到这个列表中。

📝 类的定义与实例化

  • 类的定义:在Python中,类的定义通过class关键字进行。DormManagementSystem类定义了一个构造函数__init__,该函数初始化了两个空列表dormsstudentsdorms列表用于存储Dorm类的实例对象,而students列表用于存储Student类的实例对象。

  • 实例化:在类的定义中,dormsstudents都是类的属性。通过self.dorms = []self.students = [],我们为每个DormManagementSystem实例创建了这两个列表。

🔧 方法的实现

  • add_dorm方法add_dorm方法接受一个Dorm类的实例对象作为参数,并将其添加到dorms列表中。具体实现如下:

    def add_dorm(self, dorm):
        self.dorms.append(dorm)
    

    这里,dorm是一个Dorm类的实例对象,通过self.dorms.append(dorm),我们将其添加到dorms列表中。

  • add_student方法:类似地,add_student方法接受一个Student类的实例对象作为参数,并将其添加到students列表中。具体实现如下:

    def add_student(self, student):
        self.students.append(student)
    

    这里,student是一个Student类的实例对象,通过self.students.append(student),我们将其添加到students列表中。

🔗 关联与操作

  • assign_student_to_dorm方法:该方法用于将Student类的实例对象分配到Dorm类的实例对象中。具体实现如下:

    def assign_student_to_dorm(self, student, dorm):
        if student in self.students and dorm in self.dorms:
            dorm.add_student(student)
        else:
            print("学生或宿舍不存在,无法分配。")
    

    这里,studentdorm分别是StudentDorm类的实例对象。通过dorm.add_student(student),我们将student添加到dormstudents列表中。

  • remove_student_from_dorm方法:该方法用于从Dorm类的实例对象中移除Student类的实例对象。具体实现如下:

    def remove_student_from_dorm(self, student, dorm):
        if student in self.students and dorm in self.dorms:
            dorm.remove_student(student)
        else:
            print("学生或宿舍不存在,无法移除。")
    

    这里,studentdorm分别是StudentDorm类的实例对象。通过dorm.remove_student(student),我们从dormstudents列表中移除student

📊 数据结构与逻辑

  • 数据结构DormManagementSystem类中的dorms列表是一个存储Dorm类实例对象的列表。每个Dorm实例对象又包含一个students列表,用于存储Student类的实例对象。这种嵌套的数据结构使得我们可以通过DormManagementSystem类来管理多个宿舍和学生。

  • 逻辑操作:通过add_dormadd_studentassign_student_to_dormremove_student_from_dorm等方法,我们可以对dormsstudents列表进行增删改查操作,从而实现对宿舍和学生的管理。

🛠️ 解决方案与操作步骤

  • 解决方案:为了实现对宿舍和学生的管理,我们可以通过定义DormManagementSystem类,并在其中定义相应的方法来操作dormsstudents列表。具体步骤如下:

    1. 定义类:定义StudentDormDormManagementSystem类,并在每个类中定义相应的属性和方法。
    2. 实例化对象:通过DormManagementSystem类的实例化对象,创建宿舍和学生的实例对象,并将其添加到相应的列表中。
    3. 操作对象:通过调用DormManagementSystem类的方法,对宿舍和学生进行增删改查操作。
  • 操作步骤

    1. 创建DormManagementSystem实例dms = DormManagementSystem()
    2. 添加宿舍dms.add_dorm(Dorm("A楼1号楼", 1, 6))
    3. 添加学生dms.add_student(Student("张三", 20, "男", "20230001"))
    4. 分配学生到宿舍dms.assign_student_to_dorm(dms.students[0], dms.dorms[0])
    5. 获取宿舍学生信息print(dms.get_dorm_students(dms.dorms[0]))
    6. 移除宿舍学生dms.remove_student_from_dorm(dms.students[0], dms.dorms[0])

通过上述步骤,我们可以实现对宿舍和学生的有效管理。
