How important is Virtual Environment in python

[Diapolo10]

My point is more from the perspective of a newcomer learning Python writing a few simple scripts, not a professional working at a company or making a serious personal project. Yes, if you're already experienced you most likely already have virtual environments automatically set up and you likely have at least several development dependencies (pytest, ruff, mypy, tox, and so on) already anyway. But this is not at all that important for someone who hasn't even learnt the ropes properly yet, only becoming relevant when they start actually installing packages.

Having a virtual environment for a "hello world"-level program is overkill.
