Answer:Here's the implementation of the LibraryCatalog class based on the provided requirements:The code defines a LibraryCatalog class to represent a catalog for a library.The class has attributes for the name of the catalog and a list to store the books in the catalog.The class provides methods to add books to the catalog, remove books from the catalog, search for books by title, compare catalogs, group books by year, and search for books by author.The code tests the functionality of the LibraryCatalog class by creating an instance of the catalog, adding books to it, searching for books, removing books, comparing catalogs, grouping books by year, and searching for books by author.The output shows the results of each operation, including messages for adding, removing, and searching for books, as well as the string representation of the catalog at various stages.The code also handles scenarios where books are not found or where there are no common books between catalogs, and provides appropriate messages for those cases.Overall, the code demonstrates the basic functionality of a library catalog and showcases how to perform various operations on the catalog using the defined methods of the LibraryCatalog class.
