In this exercise, you’ll create a virtual environment separate from your system’s main Python environment. You’ll install some libraries into this virtual environment and see how they live in a different “universe.”
Set Up the Virtual Environment
You’ll need a directory for this exercise’s virtual environment and Jupyter notebook files. Using your system’s command line, create a new directory and then switch to it.

Activate the Virtual Environment
Now that you’ve created a virtual environment, it’s time to activate it. Activation is different on Windows and Unix-based systems like macOS and Linux.

Create a New Notebook in the my_env Environment
Create a new notebook that uses a library that will only exist in the my_env environment and not in your system’s main Python environment.
