2.2 Project Folder and venv

By Last updated:

Keep course labs in one folder, e.g. ~/datascience-labs or C:\datascience-labs.

Steps — venv

  1. mkdir datascience-labs then cd datascience-labs.
  2. Create venv: python -m venv .venv (or python3 -m venv .venv).
  3. Activate: - Windows CMD: .venv\Scripts\activate.bat - Windows PowerShell: .venv\Scripts\Activate.ps1 - Linux / macOS: source .venv/bin/activate
  4. Your prompt should show (.venv).

Why venv? It isolates packages so class libraries do not break other projects.
