Mini-Project: The Great Migration Dataset

Build a dataset of at least five cities that were major destinations during the Great Migration. Each record needs: city, state, arrival_decade, and a nested list called notable_institutions with two or more entries. Then answer with code: (1) how many cities are in your dataset, (2) the name of the third city, (3) the first institution listed for the second city, (4) whether city one's decade came before city four's, (5) how many institutions the last city has. Then append a sixth city and reprint the count. Both languages.
