Our VLE doesn’t allow us to embed <script> tags which is the only way that Gist allows embeds of code but I found this alternative which seems to work.

TLDR; add .pibb to the end of the shareable link

It works!

Just wish it was that easy to do from Replit – it just seems to want to show a cover image when I just want it to show the main.py file. Grrr!
