前言
很多图书馆都有自己的图书管理系统，它主要担负的功能有借书和还书，以及图书管理员对图书的操作等。
程序架构
用户登录/注册—>借书/还书/查看图书---->（管理员）添加、修改图书信息
前期准备
txt文件
首先，在任意位置创建一个文件夹，创建以下几个txt文件：
bookISDN,ISDN.txt:存储书籍的ISDN编号
can lend,lended.txt:存储书籍名称
number,usrinfo.txt:存储用户名，密码
point.txt:存储每个账号还能借出的图书本书
per.txt:存储权限文件
代码准备
因为这个程序会涉及到大量的文件读取，所以我们可以用def函数来简化过程：
def open_wf(name,write):#写入txt（覆盖）
str(write)
with open(name,"w",encoding="utf-8") as f:
f.write(write)
f.close()
return True
def open_wj(name,write):#写入txt（不覆盖）
str(write)
with open(name,"a",encoding="utf-8") as f:
f.write(write)
f.close()
return True
def open_r(name):#读取（仅第一行）
with open (name,"r",encoding="utf-8") as f:
data = f.readline()
f.close()
return data
def open_r1(name):#全部读取
with open (name,"r",encoding="utf-8") as f:
data = f.readlines()
f.close()
return data
def now():
times=time.localtime()
now=str(times.tm_hour)+":"+str(times.tm_min)+":"+str(time.tm_sec)
return now
def msgbox(flag,word):
if flag=="1":
print(word)
elif flag=="2":
print(word)
