is the bash stuff necessary? could this be more confusing to someone who has never dealt with a programming language before?
when running the flashing led cell, it might be worth mentioning that they won't have control of the notebook while the loop is running.
absolutely not into using zip
might be worth explaining a bit more about loops in general. maybe this could be in notebook 1. Just something that prints out the numbers 0-9 so they get a sense of what for led_num in range(board.buttons.length) means.
might want to turn off all the leds again before the 'reacting to button presses' section.

See PR #12 for the changes based on this. Main notes are:

I agree that some of the bash examples looked frightening, so I've removed them all except the hostname cell. My reasoning is:
1. I wanted to demonstrate that the code really is running on the board and this is awkward to do via Python before explaining LED I/O
2. More importantly, the ! bash calls are used in some of the later notebooks for apt installing things and here is a nice place to tee that up.
"absolutely not into using zip" - Don't want to concede any FP ground but I think you've made the right call...

Thanks for looking through this!
