"5 Ways to Use Lists and Dictionaries to Keep track of Information"

Sure, I can create examples for you for both list and dictionary data structures. **Example 1, Using a List for Student Names:** You might have a list of student names in a classroom. For example: ```python students = ['John', 'Sarah', 'Bob', 'Alice', 'Matthew', 'Bella'] ``` To add a new student in the list, you would use the `append()` method: ```python students.append('Michael') ``` The list now becomes: ```python ['John', 'Sarah', 'Bob', 'Alice', 'Matthew', 'Bella', 'Michael'] ``` To remove a student from the list you'd use the `remove()` method: ```python students.remove('Bob') ``` **Example 2, Using a Dictionary for a Library Catalog:** A Python dictionary would be useful to store a library catalog where the books' ISBN function as the key with the value being a further dictionary of other book properties such as title, author, and year of publication. ```python library_catalog = { '978-3-16-148410-0': { 'title': 'To Kill a Mockingbird', 'author': 'Harper Lee', 'year': '1960' }, '978-0-07-180925-2': { 'title': 'The Great Gatsby', 'author': 'F. Scott Fitzgerald', 'year': '1925' } } ``` To add a new book you'd add another item to the dictionary: ```python library_catalog['978-0-201-63385-3'] = {'title': 'A Brief History of Time', 'author': 'Stephen Hawking', 'year': '1988'} ``` To remove a book from the dictionary, you'd use the `del` statement: ```python del library_catalog['978-3-16-148410-0'] ``` Note that the keys in the dictionary are unique and there can't be two identical keys, which perfectly meets the need for unique ISBNs for each book.
