Creating a Random Image Chooser in Tkinter with Python

Are you looking to add some fun functionality to your Python Tkinter application? Perhaps you want to create a random image chooser that will display images stored in the same folder as your script? Let’s tackle this project together! In this guide, we will fix a common issue faced by beginners when coding a random image selector using Tkinter.

The Problem

Your initial attempt at choosing a random image looks like this:

This code snippet does not work as expected because gen1 is an integer and cannot be directly concatenated with a string. Let's break down the solution to this problem.

The Solution

Here's how we can resolve the issue:

Step 1: Import Necessary Libraries

Ensure you have the necessary libraries imported at the start of your script:

Step 4: Correctly Open the Image

This is where the initial implementation fell short. You need to convert the integer to a string before concatenating it with the .png extension. Replace your image opening line with the following:

This ensures that gen1, which is an integer, is correctly converted to a string before the file name is constructed.

Step 5: Display the Image

Now that the image file is correctly referenced, you can create a label to display it and pack it in the window:
