吴海东：My Blog:http://www.cnblogs.com/whd-67270

二，程序说明

1. 查询员工工资

2. 修改员工工资

3. 增加新员工记录

4. 退出

三，程序前准备

创建一个存放员工信息的文件，里面记录员工的姓名和工资

四，程序脚本

def file_test():
    with open("yuangong.txt",‘r‘,encoding="utf-8") as f:
        file = list(f)
        return file

def server():
    for i in range(1):
        print("1.查询员工工资\n2.修改员工工资\n3.增加新员工记录\n4.退出")
        return i
loginSucces = False
while True:
        i = server()
        serial_number = input("请选择你的服务:")
        if serial_number.isdigit():
            serial_number = int(serial_number)
            file = file_test()
            if serial_number < 4 and serial_number >= 0:
                if serial_number == 1:
                    name = input("请输入要查询的员工姓名:").strip()
