I realize that even $2 systems are running full Linux distros these days but Python does not map to what I think of as “embedded”. If you have a full Python interpreter, it is already a pretty rich environment.
That said, this is what computing is starting to look like. There is less and less “bare metal”. I work with people that claim to be “firmware” engineers and then, when you look, you find out they have a full Ubuntu distro running and they may as well be running on a laptop.
