python使用模块写一个宿舍管理系统

好的，宿舍管理系统可以包含以下功能：

1. 学生信息管理：包括添加学生信息、修改学生信息、查询学生信息、删除学生信息等功能；
2. 宿舍信息管理：包括添加宿舍信息、修改宿舍信息、查询宿舍信息、删除宿舍信息等功能；
3. 入住管理：包括学生入住、学生退房、查询入住信息等功能；
4. 统计管理：包括宿舍入住率统计、宿舍费用统计等功能。

下面是一个简单的宿舍管理系统的实现：

1. 学生信息管理模块：

class Student:
    def __init__(self, name, gender, department, grade, phone):
        self.name = name
        self.gender = gender
        self.department = department
        self.grade = grade
        self.phone = phone

class StudentManager:
    def __init__(self):
        self.students = []

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

    def delete_student(self, name):
        for student in self.students:
            if student.name == name:
                self.students.remove(student)

    def modify_student(self, name, gender, department, grade, phone):
        for student in self.students:
            if student.name == name:
                student.gender = gender
                student.department = department
                student.grade = grade
                student.phone = phone

    def search_student(self, name):
        for student in self.students:
            if student.name == name:
                return student

    def show_students(self):
        for student in self.students:
            print(student.name, student.gender, student.department, student.grade, student.phone)

2. 宿舍信息管理模块：

class Dormitory:
    def __init__(self, dorm_id, dorm_type, dorm_fee, dorm_status):
        self.dorm_id = dorm_id
        self.dorm_type = dorm_type
        self.dorm_fee = dorm_fee
        self.dorm_status = dorm_status

class DormitoryManager:
    def __init__(self):
        self.dormitories = []

    def add_dormitory(self, dormitory):
        self.dormitories.append(dormitory)

    def delete_dormitory(self, dorm_id):
        for dormitory in self.dormitories:
            if dormitory.dorm_id == dorm_id:
                self.dormitories.remove(dormitory)

    def modify_dormitory(self, dorm_id, dorm_type, dorm_fee, dorm_status):
        for dormitory in self.dormitories:
            if dormitory.dorm_id == dorm_id:
                dormitory.dorm_type = dorm_type
                dormitory.dorm_fee = dorm_fee
                dormitory.dorm_status = dorm_status

    def search_dormitory(self, dorm_id):
        for dormitory in self.dormitories:
            if dormitory.dorm_id == dorm_id:
                return dormitory

    def show_dormitories(self):
        for dormitory in self.dormitories:
            print(dormitory.dorm_id, dormitory.dorm_type, dormitory.dorm_fee, dormitory.dorm_status)

3. 入住管理模块：

class CheckinManager:
    def __init__(self, student_manager, dormitory_manager):
        self.student_manager = student_manager
        self.dormitory_manager = dormitory_manager
        self.checkins = []

    def checkin(self, name, dorm_id):
        student = self.student_manager.search_student(name)
        dormitory = self.dormitory_manager.search_dormitory(dorm_id)
        if student and dormitory and dormitory.dorm_status == '空闲':
            dormitory.dorm_status = '已入住'
            self.checkins.append((student, dormitory))
            print('入住成功！')
        else:
            print('入住失败！')

    def checkout(self, name, dorm_id):
        student = self.student_manager.search_student(name)
        dormitory = self.dormitory_manager.search_dormitory(dorm_id)
        if student and dormitory and dormitory.dorm_status == '已入住':
            dormitory.dorm_status = '空闲'
            self.checkins.remove((student, dormitory))
            print('退房成功！')
        else:
            print('退房失败！')

    def search_checkin(self, name):
        for checkin in self.checkins:
            if checkin[0].name == name:
                print(checkin[0].name, checkin[1].dorm_id)

    def show_checkins(self):
        for checkin in self.checkins:
            print(checkin[0].name, checkin[1].dorm_id)

4. 统计管理模块：

class StatisticsManager:
    def __init__(self, dormitory_manager, checkin_manager):
        self.dormitory_manager = dormitory_manager
        self.checkin_manager = checkin_manager

    def dormitory_occupancy_rate(self, dorm_type):
        dormitories = self.dormitory_manager.dormitories
        count = 0
        for dormitory in dormitories:
            if dormitory.dorm_type == dorm_type and dormitory.dorm_status == '已入住':
                count += 1
        occupancy_rate = count / len(dormitories)
        print(dorm_type + '入住率为：' + str(occupancy_rate))

    def dormitory_fee_statistics(self, dorm_type):
        dormitories = self.dormitory_manager.dormitories
        total_fee = 0
        for dormitory in dormitories:
            if dormitory.dorm_type == dorm_type and dormitory.dorm_status == '已入住':
                total_fee += dormitory.dorm_fee
        print(dorm_type + '总费用为：' + str(total_fee))

以上就是一个简单的宿舍管理系统的实现。在实际开发中，还可以加入更多的功能，例如管理员登录、密码验证、异常处理等。
