Today I have been toying around with jupyter.
I wanted to know how it works (since I use it with Python all the
time).
I was trying to couple xeus[3] with drepl[4] together.
But now (after using google and not duckduckgo), I have found
multiple projects, which attempted similar things.

Hi, forum
I have two questions:
