基于Python編寫一個(gè)點(diǎn)名器的示例代碼_python

作者：晉升閣 ? 更新時(shí)間： 2022-08-25 編程語言

前言

想起小學(xué)的時(shí)候老師想點(diǎn)名找小伙伴回答問題的時(shí)候，老師竟斥巨資買了個(gè)點(diǎn)名器。今日無聊便敲了敲小時(shí)候老師斥巨資買的點(diǎn)名器。

本人姓白，就取名小白點(diǎn)名器啦，嘿嘿

代碼包含：添加姓名、查看花名冊(cè)、使用指南、隨機(jī)抽取名字的功能（完整源碼在最后）

主界面

定義主界面。使用“w+”模式創(chuàng)建test.txt文件（我添加了個(gè)背景圖片，若不需要可省略）

#打開時(shí)預(yù)加載儲(chǔ)存在test.txt文件中的花名冊(cè)
namelist = []
with open("test.txt", "r") as f:
    for line in f.readlines():
        line = line.strip('\n')
        namelist.append(line)
win = Tk()
win.title('小白點(diǎn)名器')
win.geometry('500x300')
#定義畫布，添加背景圖片
canvas = Canvas(win,width=500,height=300)
img_obj = PhotoImage(file=r"C:\Users\ge\Downloads\IMG_202206307919_png.png") #需輸入照片路徑
image = canvas.create_image(250,0,anchor = "n" , image = img_obj)
canvas.pack()
a = StringVar()
b = StringVar()
b.set('開始')
#定義可變文本信息
Label1 = Label(win, textvariable=a, font=('黑體', 100)).place(y= 60 , x=65)
#定義四個(gè)按鈕
Button1 = Button(win, textvariable=b, font=('等線', 30), command = zhuanzhuan).place(y=210,x = 190)
Button2 = Button(win, text = '添加姓名', font=('等線', 20), command = addname).place(x= 50,y =0)
Button3 = Button(win, text = '查看', font=('等線', 20), command = chakan).place(x= 230,y =0)
Button4 = Button(win, text = '指南', font=('等線', 20), command = zhinan).place(x= 360,y =0)
win.mainloop()

添加姓名

定義添加姓名界面，每添加一次姓名就保存到test.txt文件中，判斷輸入是否為空（添加提示框）、判斷花名冊(cè)是否為空。

#定義添加姓名界面
def addname():
    global Entry1
    window = Tk()
    window.title('姓名添加器')
    window.geometry('400x200+500+200')
    Label11 = Label(window, text = '請(qǐng)?jiān)谙路捷斎肽阋砑拥男彰?, font=('黑體', 18), anchor='center').place(y=30, x=25)
    Entry1 = Entry(window, font=('等線', 30), width=70)
    Entry1.place(y=80, x=70, width=200, height=80)
    Button3 = Button(window, text = '確認(rèn)', font=('等線', 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 #聲明為全局變量實(shí)時(shí)更新
    if len(Entry1.get()) == 0:
        tkinter.messagebox.showinfo('提示', '姓名輸入不能為空哦')
    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)

查看花名冊(cè)

這個(gè)比較簡單，使用Text來顯示字典內(nèi)的信息即可

def chakan():
    window = Tk()
    window.title('花名冊(cè)查看')
    window.geometry('350x200+500+200')
    console = Text(window, font=('等線', 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顯示?

def zhinan():
 
    window = Tk()
    window.title('小白點(diǎn)名器使用指南')
    window.geometry('350x230+500+200')
    console = Text(window, font=('等線', 11))
    console.place(y=20, x=35, width=280, height=190)
    console.insert(1.0, '                歡迎使用小白點(diǎn)名器1.0\n你可以在”添加姓名按鈕上輸入你要添加的名字\n你可以在”查看“按鈕中查看花名冊(cè)中所有的名字'
                        '\n你可以在此程序同級(jí)的名為”花名冊(cè).txt“的文件夾中直接批量添加、刪減姓名(使用回車做分隔)\n--------------------------------\n'
                        '(指南之外)此程序在CSDN中已開源,歡迎訪問我的博客：晉升閣\n需要合作的可加我微信：baijinge1137')

名字轉(zhuǎn)動(dòng)功能

判斷“開始”、“停止”狀態(tài)。定義線程。啟用一個(gè)線程

#判斷狀態(tài)
def zhuanzhuan():
    if b.get() == '開始':
        b.set('停止')
    elif b.get() =="停止":
        b.set('開始')
    _thread.start_new_thread(xiancheng,()) #啟用一個(gè)線程來轉(zhuǎn)動(dòng)姓名
#定義一個(gè)線程
def xiancheng():
    global xuanzhong
    while b.get()=='停止':
        try:
            xuanzhong = random.choice(namelist)
            a.set(xuanzhong)
            Label1.updata()#刷新數(shù)據(jù)
            time.sleep(0.3)#0.3秒刷新一次
        except:
            continue
            time.sleep(0.3)
    a.set(xuanzhong)

完整代碼

提示：我的項(xiàng)目是在主界面添加了背景圖片的，若是不需要添加背景圖片可刪掉90-94行代碼。若是需要添加背景圖片的需注意路徑地址是否正確
