前言
想起小学的时候老师想点名找小伙伴回答问题的时候,老师竟斥巨资买了个点名器。今日无聊便敲了敲小时候老师斥巨资买的点名器。
本人姓白,就取名小白点名器啦,嘿嘿
代码包含:添加姓名、查看花名册、使用指南、随机抽取名字的功能(完整源码在最后)
主界面
定义主界面。使用“w+”模式创建test.txt文件(我添加了个背景图片,若不需要可省略)
#打开时预加载储存在test.txt文件中的花名册 namelist = [] with open("test.txt", "r") as f: for line in f.readlines(): line = line.strip('\n') namelist.append(line) win = Tk() win.title('小白点名器') win.geometry('500x300') #定义画布,添加背景图片 canvas = Canvas(win,width=500,height=300) img_obj = PhotoImage(file=r"C:\Users\ge\Downloads\IMG_202206307919_png.png") #需输入照片路径 image = canvas.create_image(250,0,anchor = "n" , image = img_obj) canvas.pack() a = StringVar() b = StringVar() b.set('开始') #定义可变文本信息 Label1 = Label(win, textvariable=a, font=('黑体', 100)).place(y= 60 , x=65) #定义四个按钮 Button1 = Button(win, textvariable=b, font=('等线', 30), command = zhuanzhuan).place(y=210,x = 190) Button2 = Button(win, text = '添加姓名', font=('等线', 20), command = addname).place(x= 50,y =0) Button3 = Button(win, text = '查看', font=('等线', 20), command = chakan).place(x= 230,y =0) Button4 = Button(win, text = '指南', font=('等线', 20), command = zhinan).place(x= 360,y =0) win.mainloop()
添加姓名
定义添加姓名界面,每添加一次姓名就保存到test.txt文件中,判断输入是否为空(添加提示框)、判断花名册是否为空。
#定义添加姓名界面 def addname(): global Entry1 window = Tk() window.title('姓名添加器') window.geometry('400x200+500+200') Label11 = Label(window, text = '请在下方输入你要添加的姓名', font=('黑体', 18), anchor='center').place(y=30, x=25) Entry1 = Entry(window, font=('等线', 30), width=70) Entry1.place(y=80, x=70, width=200, height=80) Button3 = Button(window, text = '确认', font=('等线', 18), command = addname1).place(x= 300,y =80, height=80) #每添加一次姓名就保存到test.txt文件中 def addname1(): global namelist #声明为全局变量实时更新 if len(Entry1.get()) == 0: tkinter.messagebox.showinfo('提示', '姓名输入不能为空哦') else: if len(Entry1.get()) == 2: zhongjian = list(Entry1.get())[::1] zhongjian1 = zhongjian[0] + ' ' +zhongjian[1] if len(namelist) == 0: nam = zhongjian1 else: nam = '\n' + zhongjian1 else: if len(namelist) == 0: nam = str(Entry1.get()) else: nam = '\n' + str(Entry1.get()) with open("test.txt", "a") as f: f.write(nam) tip = '姓名:' + Entry1.get() + ' 添加成功' tkinter.messagebox.showinfo('提示', tip) print(nam) namelist = [] with open("test.txt", "r") as f: for line in f.readlines(): line = line.strip('\n') namelist.append(line)
查看花名册
这个比较简单,使用Text来显示字典内的信息即可
def chakan(): window = Tk() window.title('花名册查看') window.geometry('350x200+500+200') console = Text(window, font=('等线', 11)) console.place(y=20, x=35, width=280, height=170) console.insert(1.0,namelist)
使用指南
同上,使用Text显示
def zhinan(): window = Tk() window.title('小白点名器使用指南') window.geometry('350x230+500+200') console = Text(window, font=('等线', 11)) console.place(y=20, x=35, width=280, height=190) console.insert(1.0, ' 欢迎使用小白点名器1.0\n你可以在”添加姓名按钮上输入你要添加的名字\n你可以在”查看“按钮中查看花名册中所有的名字' '\n你可以在此程序同级的名为”花名册.txt“的文件夹中直接批量添加、删减姓名(使用回车做分隔)\n--------------------------------\n' '(指南之外)此程序在CSDN中已开源,欢迎访问我的博客:晋升阁\n需要合作的可加我微信:baijinge1137')
名字转动功能
判断“开始”、“停止”状态。定义线程。启用一个线程
#判断状态 def zhuanzhuan(): if b.get() == '开始': b.set('停止') elif b.get() =="停止": b.set('开始') _thread.start_new_thread(xiancheng,()) #启用一个线程来转动姓名 #定义一个线程 def xiancheng(): global xuanzhong while b.get()=='停止': try: xuanzhong = random.choice(namelist) a.set(xuanzhong) Label1.updata()#刷新数据 time.sleep(0.3)#0.3秒刷新一次 except: continue time.sleep(0.3) a.set(xuanzhong)
完整代码
提示:我的项目是在主界面添加了背景图片的,若是不需要添加背景图片可删掉90-94行代码。若是需要添加背景图片的需注意路径地址是否正确
