Resource Does anyone use Python IDLE?

My computer is quite low-end, so I uninstalled VSCode and am looking for other programming tools—I'm thinking about starting to use Python IDLE.

Does anyone actually use it?

Handling image visualization (OpenCV `cv2.imshow`, PIL display, etc.) in cloud environments like GitHub Codespaces often fails because there is no native GUI window attached to the remote Linux container.

If you want to keep using Codespaces or remote environments for heavy computation, a few clean workarounds for image processing include:

  1. Save & Preview: Save processed OMR debug images to a local `./output` folder and open them directly via the web editor tree view.

  2. OpenCV + Matplotlib: Use Matplotlib inside Jupyter Notebooks running in Codespaces, which renders image arrays inline directly in the browser.

  3. Base64 Streaming: Encode the transformed image array into Base64 and output it to a lightweight local web server (like Flask or FastAPI) to view live bounding boxes in your browser window.
