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

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()

mainloop()

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()
