I must admit that I had heard of repl.it in the past, but never gave it a thought.

I tend to use Jupyter because it's easy to sho, relatively easy to use, and I can distribute its documents. But installing it gives newcomers a lot of trouble, which is a shame.

I'll look more at repl.it! I'm not sure if/when/how I'll use it, but knowing about additional, newbie-friendly tools is crucial in my line of work, and helps me to improve my classes.
