Thanks much. After blowing up my LMDE installation by removing the default linux system Python with the -Purge option, I needed to figure this out. (I could not install Pandas and other things).
So, all is working fine now and I can easily create and use VENV's without concern of new packages failing to install, or corrupting/overwriting existing packages.
Also of note... after creating and activating a new VENV, I can use "python" and "pip" rather than "python3" and "pip3" in the VENV!! Although both python and python3 both work just fine - the same with a "which" command.
