笔者是一名学生，见到很多教师会选择用抽号的方式点名、收作业，甚至来确定期末口语考试的背诵文章，特花了几天时间，查阅了大量资料，完成了此抽号器。闲话不多说，进入正题。

界面是这样的：

功能是这样的：

随机抽取学号结果保存至本地修改字体及大小

代码是这样的：

首先画出一个窗口： 1 def __init__(self): 2 chuangkou= Tk() 3 chuangkou.title("随机抽取学号") 4 chuangkou.geometry('800x500') 5 6 menu=Menu(chuangkou) 7 8 submenuwenjian=Menu(menu,tearoff=0) 9 submenuwenjian.add_command(label="保存到",command=self.lingcunwei,font=("宋体",12,"normal")) 10 menu.add_cascade(label="文件",menu=submenuwenjian,font=("宋体",12,"normal")) 11 12 geshi=Menu(menu,tearoff=0) 13 geshi.add_command(label="字体",command=self.zitichuang,font=("宋体",12,"normal")) 14 menu.add_cascade(label="格式",menu=geshi,font=("宋体",12,"normal")) 15 16 submenubangzhu=Menu(menu,tearoff=0) 17 submenubangzhu.add_command(label="使用说明",command=self.shiyongshuoming,font=("宋体",12,"normal")) 18 submenubangzhu.add_command(label="关于",command=self.guanyu,font=("宋体",12,"normal")) 19 menu.add_cascade(label="帮助",menu=submenubangzhu,font=("宋体",12,"normal")) 20 21 menu.add_command(label="退出",command=chuangkou.quit,font=("宋体",12,"normal")) 22 23 chuangkou.config(menu=menu) 24 25 frame1 = Frame(chuangkou) 26 frame1.pack() 27 zhanghaolabel = Label(frame1, text = "总人数：",font=("宋体",20,"normal")) 28 self.name1 = StringVar() 29 zhanghaoEntry = Entry(frame1, textvariable = self.name1,font=("宋体",18,"normal")) 30 mimalabel = Label(frame1, text = "抽取人数：",font=("宋体",20,"normal")) 31 self.name2 = StringVar() 32 mimaEntry = Entry(frame1, textvariable = self.name2,font=("宋体",18,"normal")) 33 zhucebutton = Button(frame1, text = "随机抽取",font=("宋体",20,"normal"),command = self.chouqu) 34 zhanghaolabel.grid(row = 1, column = 1) 35 zhanghaoEntry.grid(row = 1, column = 2) 36 mimalabel.grid(row = 2, column = 1) 37 mimaEntry.grid(row = 2, column = 2) 38 zhucebutton.grid(row = 3, column = 2) 39 40 frame2 = Frame(chuangkou) 41 frame2.pack(fill=BOTH,expand=1) 42 self.xianshibeichouquText=Text(frame2,font=("宋体",24,"bold")) 43 self.xianshibeichouquText.pack(fill=BOTH,expand=1) 44 45 gundongtiaoY=Scrollbar(self.xianshibeichouquText) 46 self.xianshibeichouquText['yscrollcommand']=gundongtiaoY.set 47 48 gundongtiaoY.pack(side=RIGHT,fill=Y) 49 gundongtiaoY.config(command=self.xianshibeichouquText.yview) 50 51 chuangkou.mainloop()

接着就是每个模块的方法：

抽取号码模块：

1 def chouqu(self): 2 self.xianshibeichouquText.delete(1.0,tkinter.END) 3 liebiao = [ ] 4 count=1 5 try: 6 renshu=int(self.name1.get()) 7 chouqurenshu=int(self.name2.get()) 8 if renshu
