基于PythonTK 窗口MYSQL的图书管理系统

该图书管理系统实现了用户、管理员界面的图书管理系统；在用户界面实现了查询图书、借阅图书、归还图书、捐赠图书、图书馆信息的功能。在管理员界面实现了打印缺的书单、下架图书、查询借阅记录、新进图书、查询图书信息等操作，代码简单易懂。

废话不多说直接展示Mysql中的部分表

mysql表格

读者	学号	密码	性别	班级
管理者	职工号	密码	性别	院系
书籍	编号	作者	数量	出版日期
借阅	学号	书号	借出时间	归还时间
读者号	账号	密码
管理号	账号	密码
读者	姓名	性别	学院	班级

mysql数据库代码如下：

create database library;
use library;

create table reader(rid int primary key,
rname char(20) not null ,
rsex char(5) not null,
class char(20),
bleft int);

create table managers(rid int primary key,
mname char(20) not null,
msex char(5) not null,
mclass char(20),
mbleft int);

create table book(bid int,
writer char(20),
num int ,
bname char(20) not null,
ptime datetime );

create table borrow(lid int,
rid int,
bid int primary key,
btime datetime ,
rtime datetime  
);
create table rpass(rid int primary key,
rpassward char(10) not null  
);
create table mpass(
mid int primary	key,
mpassward char(10)  not null );

create table reader_mess(rid int,
mingzi char(20)  ,
rsex char(5) ,
xueyuan char(50)not null,
class char(20),
bleft int
);
create table lib_mess(iname char(20) not null,
iadress char(10));

该系统是基于Python中的pyMySQL、TK 窗口完成、参考时注意修改图片位置和mysql数据库的账户密码。
