Tkinter库Button功能的问题

Question

想用tkinter库的button功能，用户点击完按钮自动关闭按钮界面然后跳转到与他相关的代码，咋弄？

root = Tk()
button1=Button(root,text='结账',relief=RAISED)
button1.pack()
button2=Button(root,text='添加',relief=RAISED)
button2.pack()
button3=Button(root,text='删除',relief=RAISED)
button3.pack()
a = root.mainloop()

谢谢！

root = Tk()
button1=Button(root,text='结账',relief=RAISED,command=函数名)
button1.pack()
button2=Button(root,text='添加',relief=RAISED,command=函数名)
button2.pack()
button3=Button(root,text='删除',relief=RAISED,command=函数名)
button3.pack()
a = root.mainloop()
