Python Virtual Environments (venv)

A Python virtual environment is a self-contained directory that contains a Python interpreter and a set of packages, allowing you to isolate your project's dependencies from the system Python environment.

Key Benefits:

Isolation: Manage dependencies for multiple projects without conflicts Portability: Easily replicate environments across different machines Version Management: Use different Python versions for different projects

Common Commands:

Linux / Mac (use python3 etc.)

python -m venv myenv: Create a new virtual environment
source myenv/bin/activate: Activate the environment (Linux/Mac)

Windows

python -m venv myproject
myproject\Scripts\activate
