main interface
Add name
Check the roster
Use guide
Name rotation function
Complete code
PrefaceI think of the time when the teacher wanted to call the names of children to answer questions in primary school , The teacher spent a lot of money to buy a roll counter . Today, I knocked on the roll counter that my teacher spent a lot of money to buy when I was a child .
My last name is Bai , It's named Xiaobai roll counter , Hey
The code contains ： Add name 、 Check the roster 、 Use guide 、 The function of randomly extracting names （ The complete source code is at the end ）
main interfaceDefine the main interface . Use “w+” Pattern creation test.txt file （ I added a background picture , If not required, it can be omitted ）
# When opened, the preload is stored in test.txt The roster in the document namelist = []with open("test.txt", "r") as f: for line in f.readlines(): line = line.strip('\n') namelist.append(line)win = Tk()win.title(' Little white roll counter ')win.geometry('500x300')# Define canvas , Add background image canvas = Canvas(win,width=500,height=300)img_obj = PhotoImage(file=r"C:\Users\ge\Downloads\IMG_202206307919_png.png") # You need to enter the photo path image = canvas.create_image(250,0,anchor = "n" , image = img_obj)canvas.pack()a = StringVar()b = StringVar()b.set(' Start ')# Define variable text information Label1 = Label(win, textvariable=a, font=(' In black ', 100)).place(y= 60 , x=65)# Define four buttons Button1 = Button(win, textvariable=b, font=(' Isoline ', 30), command = zhuanzhuan).place(y=210,x = 190)Button2 = Button(win, text = ' Add name ', font=(' Isoline ', 20), command = addname).place(x= 50,y =0)Button3 = Button(win, text = ' see ', font=(' Isoline ', 20), command = chakan).place(x= 230,y =0)Button4 = Button(win, text = ' guide ', font=(' Isoline ', 20), command = zhinan).place(x= 360,y =0)win.mainloop() Add name Define the add name interface , Every time you add a name, save it to test.txt In file , Judge whether the input is empty or not （ Add a prompt box ）、 Judge whether the roster is empty .
# Define the add name interface def addname(): global Entry1 window = Tk() window.title(' Name adder ') window.geometry('400x200+500+200') Label11 = Label(window, text = ' Please enter the name you want to add below ', font=(' In black ', 18), anchor='center').place(y=30, x=25) Entry1 = Entry(window, font=(' Isoline ', 30), width=70) Entry1.place(y=80, x=70, width=200, height=80) Button3 = Button(window, text = ' confirm ', font=(' Isoline ', 18), command = addname1).place(x= 300,y =80, height=80)# Every time you add a name, save it to test.txt In file def addname1(): global namelist # Declared as a global variable and updated in real time if len(Entry1.get()) == 0: tkinter.messagebox.showinfo(' Tips ', ' The name input cannot be empty ') 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 = ' full name :' + Entry1.get() + ' Add success ' tkinter.messagebox.showinfo(' Tips ', tip) print(nam) namelist = [] with open("test.txt", "r") as f: for line in f.readlines(): line = line.strip('\n') namelist.append(line) Check the roster This is simpler , Use Text To display the information in the dictionary
