Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Sun code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information: Name, radius, mass, and temperature. You can assume that all numerical values are of type float and use type hints in all your method signatures accordingly.

Book Donation App Create a book-app directory. The app can be used to manage book donations and track donors and books. The catalog is implemented using the following classes: 1. The app should have donors-repo.js to maintain the list of donors and allow adding, updating, and deleting donors. The donor object has donorID, firstName, lastName, and email properties. This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2. The app should have books-repo.js to maintain the list of donated books and allow adding, updating, and deleting books. The book object has bookID, title, authors, and donorID properties. • donorID references the book’s donor. This…
