How do you manage dependency isolation in your projects?

To manage dependencies isolation in Python projects, virtual environments are commonly used. They allow creating a separate space with the required library versions without affecting global packages.

Main tools:

• venv — a built-in module for creating virtual environments.
• virtualenv — an external tool with extended capabilities.
• pipenv — combines virtual environment management and dependencies.

Example of creating and activating a virtual environment using venv:

python -m venv env
source env/bin/activate  # Linux/Mac
env\Scripts\activate    # Windows
pip install -r requirements.txt

This approach helps avoid version conflicts between libraries across projects and simplifies deployment.
