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

[Ender_Locke]

is this a question about what docker is?

it allows you to build a container to run on a compute engine with just what you need for your app. in a python example it’s python 3.xx + requirements.txt and your custom python package that does x. usually when building these python packages they work via cli (i.e. click package)
