pip and venv virtual environments

[soupworks]

I am looking for some direction for venv virtual environments.

I'm running Python 3.9

If I use virtual environments with venv, I believe by default they will use my system parameters.
If I read the docs correctly, once the environment is created, I need to pip install the extra packages.
Will the new venv look on my system for the packages first, or go download another copy every time?

If I wanted to use something like netmiko, would it need to download everything again each time I create a new venv?

Thanks for any advice.
Sorry if I couldn't find the topic already in the forums.

some of the places I found useful in searching were
https://docs.python.org/3/library/venv.html
https://docs.python.org/3/tutorial/venv.html

if you have activated your venv, pip will work from it's site-packages group.
if not activated, will use system.

FYI to activate (Linux): . venvname/bin/activate

if you also use pyenv, you can have different versions of python installed in different virtual environments.
