Is there a better way to do this with docker? Automatically commit latest image when exiting.

docker run -it python && docker commit `docker ps -l | tail -1 | cut -f1 -d' '` throat

``` docker run -it python && docker commit `docker ps -l | tail -1 | cut -f1 -d' '` throat ``` What does that do? It runs a python image in interactive mode and then saves the most recently closed image to the name throat when done. It seems like a lot for something I want to do often.. saving the most recent image to a name.
