如何从tkinter调用消息框？

Question

我正在使用Python创建一个基于Tkinter的图形用户界面，遇到了一个问题：当我从输入框获取数据时，消息框没有出现。我该如何解决这个问题？

from tkinter import *
import random


win = Tk()
win.title("Sample")
win.resizable(False, False)
win.configure(bg="#767676")

def game():
    entry = Entry_field.get()
    days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Sunday", "Saturday"]
    randomise = random.choice(days)
    messagebox.showinfo("Ответ", randomise)

Label_field = Label(win, text="Choose your day!", font=("outrun", 10, "bold"))
Label_field.grid(row=0, column=0)

Notification_Label = Label(win, text="Enter your name here", font=("montserrat", 10, "bold"), bg="#EF9A9A")
Notification_Label.grid(row=1, column=0, sticky=W)

Entry_field = Entry(win, width=30)
Entry_field.grid(row=1, column=1)

Button_field = Button(win, text="Press", command=game)
Button_field.grid(row=1, column=2)

win.mainloop()

你需要将这行代码放在文件顶部：import tkinter.messagebox as messagebox。 - Ed Ward

将以下代码放在你的代码顶部，一切都会正常工作：from tkinter import messagebox。 - DaniyalAhmadSE

您正在尝试使用来自tkinter.messagebox模块的showinfo函数，但尚未导入它。 您需要在代码顶部添加import tkinter.messagebox as messagebox或from tkinter import messagebox行。这是完整的修复代码：

from tkinter import *
import tkinter.messagebox as messagebox
import random


win = Tk()
win.title("Sample")
win.resizable(False, False)
win.configure(bg="#767676")

def game():
    entry = Entry_field.get()
    days = ["Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Sunday", "Saturday"]
    randomise = random.choice(days)
    messagebox.showinfo("Ответ", randomise)

Label_field = Label(win, text="Choose your day!", font=("outrun", 10, "bold"))
Label_field.grid(row=0, column=0)

Notification_Label = Label(win, text="Enter your name here", font=("montserrat", 10, "bold"), bg="#EF9A9A")
Notification_Label.grid(row=1, column=0, sticky=W)

Entry_field = Entry(win, width=30)
Entry_field.grid(row=1, column=1)

Button_field = Button(win, text="Press", command=game)
Button_field.grid(row=1, column=2)

win.mainloop()
