venv: Python virtual environment

How to setup and use venv to create virtual environments in Python.

Overview

Virtual environments enable us to manage project-specific dependencies in python using venv.

For windows users, the virtual environment may be setup in powershell using:

python -m venv .venv

Before using it, you may first need to change execution policies in Powershell:

Set-ExecutionPolicy Unrestricted -Scope Process

Activate the virtual environment in PowerShell by running:

.venv\Scripts\Activate.ps1

Success is visible when the path begins with (.venv)

You can close the virtual environment with:

deactivate
