Hướng dẫn python windows error message

I have a program and if you enter the ip address wrong the shell window will produce a socket error. I want to create a pop up message box that runs anytime I see a certain error in the shell window.

I cant really find a whole lot of info on something like this.

You can use PySimple GUI. It's easy to implement.

For that you need to install it.

You can Install it through this command :-

pip install PySimpleGUI

Code for Invalid Ip address of generating Pop Up is as follow:-

import PySimpleGUI as sg
import socket

try:
    socket.inet_aton('256.0.0.1')
    print("Validate IP")
    # legal
except socket.error:
    # Not legal
    sg.Popup('Opps!', 'Wrong IP Address!')

Hope this Helpful !

you could do something like this if you want a popup message box if you are using windows.

import ctypes

ctypes.windll.user32.MessageBoxW(0, u"Error", u"Error", 0)

else you could use Tkinter using

import tkinter
from tkinter import messagebox

# hide main window
root = tkinter.Tk()
root.withdraw()

# message box display
messagebox.showerror("Error", "Error message")
messagebox.showwarning("Warning","Warning message")
messagebox.showinfo("Information","Informative message")

Does Tcl/Tk fit your use case?

from tkinter import *

def validate(address):
    valid = False
    # validation logic
    if not valid:
        raise Exception("Socket Error")

if __name__ == "__main__":
    ip = r"https://stackoverflow.com/"
    try:
        validate(ip)
    except Exception as e:
        root = Tk()
        w = Label(root, text=e)
        w.pack()
        root.mainloop()

The Tkinter library has many built-in functions and methods which can be used to implement the functional part of an application. We can use messagebox module in Tkinter to create various popup dialog boxes. The messagebox property has different types of built-in popup windows that the users can use in their applications.

If you need to display the error messagebox in your application, you can use showerror("Title", "Error Message") method. This method can be invoked with the messagebox itself.

Example

# Import the required libraries
from tkinter import *
from tkinter import messagebox

# Create an instance of tkinter frame or window
win = Tk()

# Set the size of the tkinter window
win.geometry("700x350")

# Define a function to show the error message
def on_click():
   messagebox.showerror('Python Error', 'Error: This is an Error Message!')

# Create a label widget
label = Label(win, text="Click the button to show the message ",
font=('Calibri 15 bold'))
label.pack(pady=20)


# Create a button to delete the button
b = Button(win, text="Click Me", command=on_click)
b.pack(pady=20)

win.mainloop()

Output

When you run the above code, it will show a button widget and a label in the window. Click the button to show the error message.
