最近学习了python的TK窗口函数，制作了一个简单的抽人小程序

运行环境：python3.7

运行效果： 

代码结构比较简单 

from tkinter import *
from tkinter import messagebox
import random

class Window(object):
    def __init__(self):
        self.window=Tk()
        self.title="抽人小程序"
        self.size=(500,200)


        
    def show(self):
        def c():   #输入格式判断
            #not e1.get()判断是否为空
            if not e1.get():   
                messagebox.showinfo("警告：","请输入序号范围下限！")
            elif not e2.get():
                messagebox.showinfo("警告：","请输入序号范围上限！")
            elif not e3.get():
                messagebox.showinfo("警告：","请输入抽取数量！")
            elif int(e1.get())>int(e2.get()) or int(e1.get())<=0 or int(e2.get())<=0:
                messagebox.showinfo("警告：","请输入正确的上下限！")
            elif int(e3.get())<=0:
                messagebox.showinfo("警告：","请输入正确的抽取数量！")
            else:
                d()
        def d():  #抽取并使用弹窗输出
            List = []
            for i in range(int(e3.get())):
                List.append(random.randint(int(e1.get()),int(e2.get())))
            messagebox.showinfo("恭喜","抽到===>{}".format(List))
            
        ##绘制窗口组件
        self.window.geometry("%dx%d"%self.size)
        self.window.title(self.title)
        ##添加序号范围输入框（获取抽取范围）
        lb1 = Label(self.window, text='请输入序号范围：')
        lb1.grid(row=0, column=0)
        v1 = StringVar()
        e1 = Entry(self.window, textvariable=v1)
        e1.grid(row=0, column=1)
        lb2 = Label(self.window, text='~')
        lb2.grid(row=0, column=2)
        v2 = StringVar()
        e2 = Entry(self.window, textvariable=v2)
        e2.grid(row=0, column=3)
        ##添加抽取数量输入框
        lb3 = Label(self.window, text='需要抽取人数：')
        lb3.grid(row=1, column=0)
        v3 = StringVar()
        e3 = Entry(self.window, textvariable=v3)
        e3.grid(row=1, column=1)
        lb4 = Label(self.window, text='人')
        lb4.grid(row=1, column=2)
        ##添加按钮，调用函数c
        button1 = Button(self.window, text='抽取', command=c)
        button1.grid(row=10, column=4, sticky=E)
        
if __name__ == '__main__':
    window=Window()
    window.show()
