Q:

How to re-run a stopped named Ubuntu in docker?

I've create an Ubuntu container in docker (on windows 10) like the following:
> docker run --name omuntu -it ubuntu

After that, I installed some packages in that named container such as python. Then, exited from the container by exit command. Now, the question is How can I start the named container again, some how run commands inside its bash and access to my previous installed packages?
I should have mentioned that docker start omuntu just run the service and I get the following on docker ps:
CONTAINER ID        IMAGE               COMMAND             CREATED             
STATUS              PORTS               NAMES
932a2859c1ca        ubuntu              "/bin/bash"         36 minutes ago      Up 3 seconds                            
omuntu

But I cannot run the command such as I've ran for the first time, as an instance , this command:
root@932a2859c1ca:/# python -V

A:

You should using two default false options --attach, -a and --interactive, -i such as below:
> docker start -ai omuntu

After that, you will get:
root@932a2859c1ca:/#

Now, you can run your command inside the Ubuntu container. Of course, the installed packages are available in this container. See more options here.
