This code snippet installs and configures Jupyter Notebook and JupyterLab, enabling the use of Python kernels and extensions.

Here's a breakdown:

1. jupyter --version: This command displays the installed version of Jupyter Notebook.

2. pip3 install jupyter jupyterlab notebook: This command uses pip3, the Python 3 package installer, to install Jupyter Notebook, JupyterLab, and the core notebook package.

3. jupyter notebook serverextension enable --py: This command enables Python kernel support for Jupyter Notebook.

4. jupyterlab --sys-prefix: This command likely configures JupyterLab to use the system's Python installation and its associated packages.

In essence, this code snippet sets up a Jupyter Notebook and JupyterLab environment, ensuring Python kernel support and proper configuration.
