ELI5 Using python virtual environment in docker container. (self.python)

I read some articles about using a virtual environment in Docker. Their argument are that the purpose of virtualization in Docker is to introduce isolation and limit conflicts with system packages etc.

However, aren't Docker and Python-based images (e.g., python:*) already doing the same thing?

Can someone eli5 this whole thing?

How can you be sure it's one line of code? What if there are several codepaths, and venvs are activated in different places? And in any case, even if there is only one conditional needed, that is still one branch more than necessary to test.

Your symlink example does not make sense. There is someting that is changing. In fact, it may even be the opposite: if you need to use file A in s container, and file B otherwise, it may make perfect sense to symlink the correct file to C, so thst your code does not need to care about it.
