+**venv** stands for virtual environment and is part of the python standard library (i.e. you don't have to install it).
+Python virtual environments' role is to create an isolated python environment for each project so that there are no dependency issues etc. from conflicting project requirements (e.g. Project A need pandas 1.0 and Project B needs pandas 1.1).  
+
 The command `python -m venv .venv` creates a directory call .venv.  
 You can activate the virtual environment with `source .venv/bin/activate`.
