How can I create a simple Python message box?

I’m looking for a similar effect to the alert() function in JavaScript.

I wrote a simple web-based interpreter using Twisted Web, where Python code is submitted through a form and then executed by the client. I want to display a simple popup message, but I don’t want to write boilerplate code for wxPython or Tkinter every time (since the form disappears after submission).

I’ve tried using tkMessageBox:

import tkMessageBox
tkMessageBox.showinfo(title="Greetings", message="Hello, World!")

However, this opens another window in the background with the Tkinter icon, which I don’t want. I was looking for a simple Python message box solution without having to set up a class or an application loop as required by wxPython. Is there an easy, catch-free way to create a Python message box?

Blessings! If you’re looking for a way to show message boxes in your Python GUI applications, using tkinter.messagebox is a simple and effective option. The issue you’re facing with tkMessageBox can be easily solved by using messagebox from the tkinter module. You still need to import Tkinter, but there’s no need to set up a full application loop, which makes it a bit simpler than using other GUI libraries. Here’s an example to show you how it works:

import tkinter as tk
from tkinter import messagebox

def show_message():
    messagebox.showinfo("Greetings", "Hello, World!")

root = tk.Tk()
root.withdraw()  # Hide the root window
show_message()

This will display a message box without having to show the entire Tkinter window, just the popup. It’s a lightweight way to handle simple alerts!

"Hello there! Just adding to what @smrity.maharishsarin mentioned, if you’re looking for something even simpler without dealing with any dependencies or GUI setup, I recommend easygui. It’s great for showing basic dialogs and message boxes without all the extra code. You can install it easily via pip:

pip install easygui

Then, it’s as simple as this:

import easygui

easygui.msgbox("Hello, World!", title="Greetings")

This will pop up a nice message box with no setup required—perfect for quick tasks without needing any complex GUI libraries!

Hey All! I just wanted to add one more option that’s super lightweight and easy to use—pymsgbox. If you want something that’s clean and simple with no extra overhead, this is a great choice. You can install it via pip as well:

pip install pymsgbox

Here’s how you can use it:

import pymsgbox

pymsgbox.alert("Hello, World!", "Greetings")

It’s a minimalistic solution that gets the job done without requiring a full GUI framework. Ideal for displaying alerts with just the essentials!
