用python实现简易图书管理系统前言程序架构前期准备txt文件代码准备
代码实现登陆系统主程序借书还书显示全部书籍添加图书
全部代码
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： 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) 代码实现 登陆系统代码： def login():
