From the rebrickable website - The LEGO Parts/Sets/Colors and Inventories of every official LEGO set in the Rebrickable database is available for download as csv files here. These files are automatically updated daily. If you need more details, you can use the API which provides real-time data, but has rate limits that prevent bulk downloading of data.

We start by checking the information in the dataset and then answering some typical questions that we may be interested in.
