首先，需要定义顾客类和员工类，分别包含会员卡号、姓名、性别、电话等信息和相关的对属性做操作的行为，以及编号、姓名、性别、电话、美发项目（理发、烫发、洗发）等信息和相关的对属性做操作的行为。 其次，需要定义美发类，包含各种美发项目的收费标准和相关的对属性做操作的行为。 接下来，需要定义一个管理类，实现添加、删除、修改、查询顾客信息和员工信息的功能。要求编号要唯一，如果添加了重复编号的记录时，则提示数据添加重复并取消添加。删除、修改、查询时，如果没有对应人员记录，则提示“记录为空！”并返回操作。 最后，需要使用外部文件存储相关数据，以便系统能够持久化保存数据 生成代码

以下是一个简单的美发店管理系统的代码示例，包括了顾客类、员工类、美发类和管理类的定义以及相关的操作函数。注意，此示例仅供参考，具体实现可根据需求进行修改和完善。

顾客类：

class Customer:
    def __init__(self, card_number, name, gender, phone):
        self.card_number = card_number
        self.name = name
        self.gender = gender
        self.phone = phone

    def get_card_number(self):
        return self.card_number

    def set_card_number(self, card_number):
        self.card_number = card_number

    def get_name(self):
        return self.name

    def set_name(self, name):
        self.name = name

    def get_gender(self):
        return self.gender

    def set_gender(self, gender):
        self.gender = gender

    def get_phone(self):
        return self.phone

    def set_phone(self, phone):
        self.phone = phone

员工类：

class Employee:
    def __init__(self, id, name, gender, phone, hairdressing):
        self.id = id
        self.name = name
        self.gender = gender
        self.phone = phone
        self.hairdressing = hairdressing

    def get_id(self):
        return self.id

    def set_id(self, id):
        self.id = id

    def get_name(self):
        return self.name

    def set_name(self, name):
        self.name = name

    def get_gender(self):
        return self.gender

    def set_gender(self, gender):
        self.gender = gender

    def get_phone(self):
        return self.phone

    def set_phone(self, phone):
        self.phone = phone

    def get_hairdressing(self):
        return self.hairdressing

    def set_hairdressing(self, hairdressing):
        self.hairdressing = hairdressing

美发类：

class Hairdressing:
    def __init__(self, name, price):
        self.name = name
        self.price = price

    def get_name(self):
        return self.name

    def set_name(self, name):
        self.name = name

使用示例：

# 创建管理类实例
management = Management()

# 添加顾客
customer = Customer("001", "张三", "男", "123456789")
management.add_customer(customer)

# 添加员工
employee = Employee("001", "李四", "男", "987654321", "理发")
management.add_employee(employee)

# 添加美发项目
hairdressing = Hairdressing("洗发", 30)
management.add_hairdressing(hairdressing)

# 查询顾客信息
management.query_customer("001")

# 修改员工信息
management.modify_employee("001", "王五", "男", "135792468", "烫发")

# 删除美发项目
management.remove_hairdressing("洗发")

# 查询美发项目信息
management.query_hairdressing("烫发")
