1设计一个数据类型（列表，元组，字典等），包括三个数据信息，分别是员工工号，员工姓名，工资，员工工号范围是1001-1101，姓名，工资不限如（1001，小明，800） 2设计一个类，实现员工查询，增加，修改，删除等功能 3员工数据信息最少5条

为了实现这个需求，我们可以设计一个名为`Employee`的类，它包含员工的基本信息，并提供相应的操作功能。我们将创建一个`EmployeeRecord`数据结构，用于存储每个员工的信息。

class EmployeeRecord:
    def __init__(self, employee_id, name, salary):
        self.employee_id = int(employee_id) if 1001 <= int(employee_id) <= 1101 else None
        self.name = str(name)
        self.salary = float(salary)

# 创建一个员工记录列表来保存至少5条数据
employee_records = [
    EmployeeRecord(1001, "小明", 800),
    EmployeeRecord(1002, "小红", 900),
    EmployeeRecord(1003, "张三", 700),
    EmployeeRecord(1004, "李四", 1000),
    EmployeeRecord(1005, "王五", 650),
]

class EmployeeDatabase:
    def __init__(self):
        self.records = employee_records

    # 员工查询
    def search_employee(self, id):
        for record in self.records:
            if record.employee_id == id:
                return record
        return None

    # 增加员工
    def add_employee(self, employee_id, name, salary):
        if 1001 <= employee_id <= 1101:
            new_record = EmployeeRecord(employee_id, name, salary)
            self.records.append(new_record)
        else:
            print("员工工号超出范围")

    # 修改员工信息
    def update_employee(self, id, new_name=None, new_salary=None):
        for record in self.records:
            if record.employee_id == id:
                if new_name is not None:
                    record.name = new_name
                if new_salary is not None:
                    record.salary = new_salary
                break

    # 删除员工
    def delete_employee(self, id):
        for index, record in enumerate(self.records):
            if record.employee_id == id:
                del self.records[index]
                break

# 使用示例
db = EmployeeDatabase()
print(db.search_employee(1001))
db.add_employee(1006, "赵六", 1200)
db.update_employee(1002, new_name="小红新名")
db.delete_employee(1004)
