This chapter requires no additional packages to install. All the code is available in the Chapter03 folder on GitHub, https://github.com/PacktPublishing/Learn-Python-by-Building-Data-Science-Applications.

To access and run example notebooks for this and other chapters, open the folder you cloned from GitHub in your VS Code, then switch to its Terminal window (that way, you're guaranteed to be in the correct folder) and type jupyter lab. On running, the application will either open a JupyterLab Notebook in your default browser or print a link. Via this link, go to the Chapter03 folder and run the Functions notebook. Once the notebook is running, you're ready to proceed!
