Tkinter messagebox弹窗

import tkinter as tk

window = tk.Tk()
window.title('my window')
window.geometry('200x200')

def hit_me():
    #tk.messagebox.showinfo(title='Hi', message='hahahaha')
    #tk.messagebox.showwarning(title='Hi', message='nononono')
    #tk.messagebox.showerror(title='Hi', message='No!! never')
    #print(tk.messagebox.askquestion(title='Hi', message='hahahaha'))   # return 'yes' , 'no'
    #print(tk.messagebox.askyesno(title='Hi', message='hahahaha'))   # return True, False
    print(tk.messagebox.asktrycancel(title='Hi', message='hahahaha'))   # return True, False
    print(tk.messagebox.askokcancel(title='Hi', message='hahahaha'))   # return True, False
    print(tk.messagebox.askyesnocancel(title="Hi", message="haha"))     # return, True, False, None

tk.Button(window, text='hit me', command=hit_me).pack()
window.mainloop()

module 'tkinter' has no attribute 'messagebox'

注意，这个问题是在windows系统上python3.5.0出现的错误。
解决方案是import tkinter.messagebox

module 'tkinter.messagebox' has no attribute 'asktrycancel'

注意：在新版本的Tkinter中，已经将方法asktrycancel改为askretrycancel
提示信息框 tk.messagebox.showinfo(title='Hi', message='hahahaha')

警告框 tk.messagebox.showwarning(title='Hi', message='nononono')

错误框 tk.messagebox.showerror(title='Hi', message='No!! never')

询问框 print(tk.messagebox.askquestion(title='Hi', message='hahahaha')) # return 'yes' , 'no'

是否框和询问框的区别在于返回的值不同 print(tk.messagebox.askyesno(title='Hi', message='hahahaha')) # return True, False

重试框询问是否重试 print(tk.messagebox.askretrycancel(title='Hi', message='hahahaha')) # return True, False

是否取消三种返回值 print(tk.messagebox.askyesnocancel(title="Hi", message="haha")) # return, True, False, None
