How to Open Python Shell and Images in Full Screen Mode with Subprocess and cv2

When developing applications or games in Python, one might encounter situations where you want your user interface components, like the Python shell and images, to open in full screen for better visibility. This can be particularly useful for projects like a hangman game, where you might be dealing with user interaction and a visual representation of words. In this guide, we will explore how to tackle this problem in a simple and effective way.

The Challenge

In this scenario, you are experiencing two main frustrations:

Image Overlayer Issue: When launching an image to display upon your game's execution, it appears behind the Python shell, making it difficult for users to notice.

Text Overflow Issue: When trying to hide the word to be guessed using a large number of newline characters (print('\n' * 100)), the text starts to go off-screen, making it harder for users to see the relevant content.

Solution Overview

To address these issues, we can utilize:

The subprocess library to manage subprocesses and system commands.

The cv2 (OpenCV) library to display images in full screen.

Let’s break down the solution into manageable parts.

Part 1: Opening Images in Full Screen

To display images in a user-friendly manner using the cv2 library, follow these steps:

Install OpenCV: If you haven't already, make sure to install OpenCV in your Python environment. You can do this using pip:

Display an Image: Use the following code snippet to open an image in a new window:

This code reads the specified image and opens it in a new window until a key is pressed.

Change Image Resolution: If you want to resize the image to fit the screen better, you can use:

Part 2: Adjusting the Python Shell Window Size

Currently, there isn't a direct feature in Python to automatically launch the shell in full screen; however, you can adjust the size of your console window using subprocess commands:

By customizing these values, you can effectively manage how much space your code outputs take up, ensuring everything is neatly displayed.

Conclusion

By incorporating cv2 to handle image displays and leveraging the subprocess library for console window management, you can significantly enhance the user experience in your Python applications. This approach not only resolves the visual overlap issue of images and the Python shell but also minimizes output overflow problems.

Remember, a clear visual representation can make a significant difference in user interaction, especially in games or educational applications. So go ahead, implement these solutions, and enjoy the improved functionality of your Python project!
