root=Tk()
width= 380height= 300
#获取屏幕尺寸以计算布局参数，使窗口居屏幕中央
screenwidth =root.winfo_screenwidth()
screenheight=root.winfo_screenheight()
alignstr= '%dx%d+%d+%d' % (width, height, (screenwidth - width) / 2, (screenheight - height) / 2)
root.geometry(alignstr)
frame=Frame(root)
frame.pack()defhit_me():#messagebox.showinfo(title='提示', message='错误')
messagebox.showwarning(title='提示', message='错误')
button= Button(frame, text='点我', command=hit_me)
button.pack()

from tkinter importmessagebox
root=Tk()
width= 380height= 300
#获取屏幕尺寸以计算布局参数，使窗口居屏幕中央
screenwidth =root.winfo_screenwidth()
screenheight=root.winfo_screenheight()
alignstr= '%dx%d+%d+%d' % (width, height, (screenwidth - width) / 2, (screenheight - height) / 2)
root.geometry(alignstr)
frame=Frame(root)
frame.pack()defhit_me():#messagebox.showinfo(title='提示', message='错误')
#messagebox.showwarning(title='提示', message='错误')
messagebox.showerror(title='提示',message='错误')

from tkinter import *
from tkinter importmessagebox
root=Tk()
width= 380height= 300

screenwidth =root.winfo_screenwidth()
screenheight=root.winfo_screenheight()
alignstr= '%dx%d+%d+%d' % (width, height, (screenwidth - width) / 2, (screenheight - height) / 2)
root.geometry(alignstr)
frame=Frame(root)
frame.pack()defhit_me():#messagebox.showinfo(title='提示', message='错误')
#messagebox.showwarning(title='提示', message='错误')
#messagebox.showerror(title='提示',message='错误')
Q = messagebox.askquestion(title='提示',message='错误') #resurn 'yes' or 'no'
print(Q)
button= Button(frame, text='点我', command=hit_me)
button.pack()
mainloop()
效果：（说明：按下是或否会返回yes或no）
