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()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)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)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'

#判断状态

except:
continue
