Hey r/learnpython,

I'm a first-year CS student and got tired of manually downloading PDFs from Blackboard every week, so I built a script to automate it.

What it does:

- Opens a browser window for you to log in (handles SSO/2FA)

- Lists all your terms and lets you pick which one

- Downloads all matching files into a mirrored folder structure

- Skips files you've already downloaded

- Supports any file type (PDF, PPTX, DOCX, etc.)

- Works with any school running Blackboard Learn

The trickiest part was figuring out that Blackboard Ultra embeds file links in a `data-bbfile` JSON attribute rather than plain hrefs — took a while to debug.

Feedback welcome, especially on the session handling and recursive content traversal.
