My question is, I have already rm python image, why it still shows already exist for some of layers? How can I totally delete all the python layers. Thanks.

Nothing. It simply ran flawless from the exact state it was before having its image deleted.
By default the Docker daemon will pull three layers of an image at a time. If you are on a low bandwidth connection this may cause timeout issues and you may want to lower this via the --max-concurrent-downloads daemon option.
Remove all images All the Docker images on a system can be listed by adding -a to the docker images command. Once you're sure you want to delete them all, you can add the -q flag to pass the image ID to docker rmi : List: docker images -a.
The 'docker pull' is a Docker command to download a Docker image or a repository locally on the host from a public or private registry. When we run any container and the specified Docker image is not present locally then it first pulls it from the registry.
From reference of docker images command
Docker images have intermediate layers that increase reusability, decrease disk usage, and speed up docker build by allowing each step to be cached. These intermediate layers are not shown by default.
Maybe those Already exists are intermediate layers. By default, they are hided when you run docker images, please try docker images --all.
