What are the differences between using a virtual environment and a global Python installation?

Using a virtual environment (venv) allows you to create isolated spaces for your projects, avoiding dependency conflicts. In contrast, a global Python installation affects all projects on your system.

Why should I use a virtual environment instead of just installing packages globally?

Using a virtual environment helps manage dependencies specific to a project, ensuring that updates or changes in one project don't break others.

Can you show me how to create a virtual environment?

Sure! You can create a virtual environment by running python -m venv myenv in your terminal, where 'myenv' is the name of your environment.

What are the commands to activate and deactivate a virtual environment?

To activate a virtual environment, use source myenv/bin/activate on macOS/Linux or myenv\Scripts\activate on Windows. To deactivate, simply run deactivate.
