how can I change what a script does while it is running, by pressing a key

[leahk]

I am trying to write code which will let the user press a key like 'b' and run an operation, while a script is still running, and have the script continue afterwards. How can I do this??? I am using Linux. working in python

#!/bin/bash

while read -p '> ' -r -n1; do
echo
case $REPLY in
b)
echo "b stuff..."
;;
l)
ls
;;
q)
echo "Bye bye"
break
;;
*)
echo "Huh?"
;;
esac
done

can you please explain the code and how it works. im working in python.

Well, it waits for a char from stdin and runs a set of commands based on what char it was...

Now that you specified you really meant a python script though, I don't see why that matters; a python script to do something similar will look completely different.
