How does a program like blender (which is written in cpp and python) run with no installation?

You can load blender onto a usb stick and just run it from there. Also, since it's partly written in python, does an interpreter get packages with the software? If not, does the software require an interpreter to be installed on the running system?

Installation means copying the files from somewhere to your computer. If the files are already there, like on a USB stick, then what's the difference if they are copied to your computer or not? They can run the same either way.

Blender includes all packages, interpreters, and other dependencies it has with it, so it doesn't need to get them from anywhere.
