How to Create a Pop-up Window in Python

Creating a pop-up window in Python can be accomplished through various methods, depending on the context and the libraries you’re using. One of the simplest ways to create a basic pop-up window is by using the tkinter library, which is Python’s standard GUI (Graphical User Interface) toolkit. Below is a step-by-step guide on how to use tkinter to create a pop-up window.

Step 1: Import the tkinter Library

First, you need to import the tkinter library. If you’re using Python 3.x, the library is named tkinter (all lowercase), whereas in Python 2.x, it was called Tkinter (with a capital ‘T’).

pythonCopy Code
import tkinter as tk

Step 2: Create the Main Window

Next, create the main window. This step is necessary even if you just want a pop-up window, as tkinter uses this main window as the base for all GUI elements.

pythonCopy Code
root = tk.Tk()
root.withdraw()  # Use this to hide the main window

Step 3: Create the Pop-up Window

Now, create the pop-up window. This can be done by creating a new Toplevel window.

pythonCopy Code
pop_up = tk.Toplevel(root)
pop_up.title("Pop-up Window")
pop_up.geometry("300x100")  # Set the size of the pop-up window

Step 4: Add Content to the Pop-up Window

You can add any content you want to the pop-up window, such as text, buttons, or other widgets.

pythonCopy Code
label = tk.Label(pop_up, text="This is a pop-up window.")
label.pack(pady=20)  # Add some padding

Step 5: Run the Application

Finally, start the application. This will display the pop-up window.

pythonCopy Code
root.mainloop()

Putting all these steps together, you get a simple script that creates a pop-up window with a message.

pythonCopy Code
import tkinter as tk

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

pop_up = tk.Toplevel(root)
pop_up.title("Pop-up Window")
pop_up.geometry("300x100")

label = tk.Label(pop_up, text="This is a pop-up window.")
label.pack(pady=20)

root.mainloop()

This script creates a simple pop-up window with the message “This is a pop-up window.” You can customize the window by adding more widgets, changing its size, or modifying other attributes.
