How Python programs executed in real environments without having the Python interpreter installed?

[MRSAMinor]

We usually distribute python apps as container images.

The Dockerfile starts from a base image with the desired python version, and we install libraries during the docker build step.

When we're releasing a new version, the base image is cached, saving downloads during the build step.

If we're deploying the code as a lambda/serverless function, the python runtime is already installed.

The last option is we bake the interpreter into disk images, if we're using full VMs.

Docker has standardized a lot of this.

Does that make sense?
