该项目主要功能,图书的增删查改,借阅证的增、删;借阅证用于结借书管理;借阅证分为老师和学生,numbers为借阅状态:

项目使用mysql数据库,表为3张:

先看运行主界面及功能:

 主页面实现代码:

initwin(): #主窗口     def __init__(self,master):         global im         global image         self.master=master         self.master.config(bg='Magenta')         self.initwin=tk.Frame(self.master,)         self.initwin.pack()         self.canvas = tk.Canvas(self.initwin,           width = 1000,               height = 700,              bg = 'green')                        image=Image.open('bg.jpg')         im=ImageTk.PhotoImage(image)          self.canvas.create_image(0,0,anchor='nw',image = im)      # 使用create_image将图片添加到Canvas组件中            self.canvas.pack()         # 将Canvas添加到主窗口         btn_add=ttk.Button(self.initwin,text="图书入库或修改信息",command=self.add)         btn_query=ttk.Button(self.initwin,text="查询图书信息",command=self.query)         btn_card=ttk.Button(self.initwin,text="借书证管理",command=self.card)         btn_borrow=ttk.Button(self.initwin,text="借书",command=self.borrow)         btn_return=ttk.Button(self.initwin,text="还书",command=self.returnbook)#return是保留字。。。          self.canvas.create_window(100,50,width=200,height=40,window=btn_add)         self.canvas.create_window(100,100,width=200,height=40,window=btn_query)         self.canvas.create_window(100,250,width=200,height=40,window=btn_card)         self.canvas.create_window(100,150,width=200,height=40,window=btn_borrow)         self.canvas.create_window(100,200,width=200,height=40,window=btn_return)          self.title=tk.Label(self.initwin,text="图书管理系统",font=("宋体",30))         self.author=tk.Label(self.initwin,text="源代码+QQ:3125841747",font=("宋体",24))         self.canvas.create_window(400,150,anchor="nw",width=300,height=70,window=self.title)         self.canvas.create_window(400,350,anchor="nw",window=self.author)      def add(self,): #add窗口,实现的功能:选择批量入库或者单本入库,添加或是修改         self.initwin.destroy()         addwin(self.master)     def query(self):         self.initwin.destroy()         querywin(self.master)     def card(self):         self.initwin.destroy()         cardwin(self.master)     def borrow(self):         self.initwin.destroy()         borrowwin(self.master)     def returnbook(self):         self.initwin.destroy()         returnwin(self.master) 

图书入库:分为单本入库和读取记事本批量入库:

单本入库:实现对图书的增、改:

 

批量入库成功后,会在文件夹中生成日志文件:

入库图书代码实现:

addwin():     def __init__(self,master):         global im         global image         self.master=master         self.master.config(bg='GhostWhite')         self.str="此处输出状态信息"         self.addwin=tk.Frame(self.master,)         self.addwin.pack()         self.canvas = tk.Canvas(self.addwin,           width = 1000,               height = 700,              bg = 'white')                        image=Image.open('bg.jpg')         im=ImageTk.PhotoImage(image)          self.canvas.create_image(0,0,anchor='nw',image = im)      # 使用create_image将图片添加到Canvas组件中            self.canvas.pack()         # 将Canvas添加到窗口         self.btn_back=ttk.Button(self.addwin,text="返回主菜单",command=self.back)         #btn_back.pack()         self.canvas.create_window(100,50,width=200,height=40,window=self.btn_back)          self.mode=tk.IntVar() #选择入库模式(单本或者批量)          self.style_radio=ttk.Style()         self.style_radio.configure("radio.TRadiobutton",font=("微软雅黑",12),background="Aqua")          self.r1=ttk.Radiobutton(self.addwin,text="单本入库(或修改信息)",variable=self.mode,value=1,command=self.display1,style="radio.TRadiobutton")         self.r2=ttk.Radiobutton(self.addwin,text="批量入库",variable=self.mode,value=2,command=self.display2,style="radio.TRadiobutton")         self.canvas.create_window(400,50,window=self.r1)         self.canvas.create_window(400,100,window=self.r2)          self.style_label=ttk.Style()         self.style_label.configure("label.TLabel",font=("微软雅黑",14))         self.s_title=ttk.Label(self.addwin,text="状态栏",style="label.TLabel", width=30,anchor="center")         self.state=tk.Message(self.addwin,text=self.str,width=300,font=("微软雅黑",12))         self.canvas.create_window(800,100,height=50,window=self.s_title)         self.canvas.create_window(650,150,anchor="nw",width=300,window=self.state)         self.flag1=0#标记“批量入库”的控件是否存在的flag         self.flag2=0#标记“单本入库”的控件是否存在的flag         self.cflag=0#change flag,用来区分是添加一本书还是修改书的信息.为1时代表修改

查询图书可以分为:类别、书名、出版社、年份、作者、价格这几种进行查询:

 按类别查询:

按书名查询:

 按出版社查询:

 其他功能不一一演示,​​​​​​​

查询图书的代码:

借书需要有借阅证,借阅证添加操作:

拥有借阅的证号,才可以借书:

 还书 :​​​​​​​
