   • macOS/Linux: source venv/bin/activate
3. Install packages:

   pip install requests
   

4. Freeze requirements:

   pip freeze > requirements.txt
   

pipenv (Alternate)

pip install pipenv
pipenv install requests
pipenv shell

poetry (Alternate)

pip install poetry
poetry init
poetry add requests
poetry shell

Key Takeaways

• Tools like pipenv and poetry simplify dependency management.

Happy coding!
