### University Class Diagram This represents a UML (Unified Modeling Language) class diagram for a `University` class. It includes the class attributes and methods: #### Attributes: - **name : string** - Represents the name of the university as a string. #### Methods: - **__str__** - Special method to return a string representation of the object. - **add_undergrad(name, email, gpa)** - Adds an undergraduate student with specified name, email, and GPA. - **add_graduate(name, email, level)** - Adds a graduate student with specified name, email, and academic level. - **add_course(...)** - Adds a course to the university. Parameters are not specified in this diagram. - **remove_student(name) : list** - Removes a student by name and returns a list of remaining students. - **get_students(name, id, email) : list** - Retrieves a list of students based on name, ID, and email. - **get_courses(subject, number, title) : list** - Retrieves a list of courses based on subject, course number, and title. - **enroll_student(id, subject, number)** - Enrolls a student in a course identified by ID, subject, and course number. - **enrollment_report() : dict** - Generates and returns an enrollment report as a dictionary.

- **University**: - Represents the university which has students and courses. - All properties are read-only. Student and course lists cannot be retrieved by the clients. - The university is responsible for creating the objects: - `add_undergrad(name, email, gpa)` and `add_graduate(name, email, level)` methods will create and add students to the university. A student's ID will be generated automatically on the Student constructor. The data such as valid GPA values or valid Level value will be validated properly in each class's properties methods. - `add_course(subject, number, title)` will add a course. Will raise a ValueError exception if there is already a course with the same subject and number. - `get_students` and `get_courses` - Will take optionally any of the arguments and return a list of the objects students or courses respectively, that matches the search criteria. - String-based attributes are not exact match but rather that the data contain that search string. - E.g., `get_students(email="john.doe")` will return a list of students whose emails have "john.doe" in it, such as "john.doe.smith@..," "william.john.doe@...," etc. - **Clarification**: Objects (students/courses) should match all specified filters by the user. E.g., `get_courses("CSCI", 3920)` will return all courses that match both the subject and number. - **Hint**: Use default arguments and lists and sets to make your code simple. Consider having a matching list per filter and then compute the intersection; initialization will be critical for this to work. - `enroll_student(...)` will take the student's ID and the course's subject and number and will enroll the student to the course. Enrollment is kept at the student as a list of courses the student is enrolled to. - `enrollment_report()` will return a dictionary of the form key -> value, where the key is a string representing the course (concatenation of subject and number - formatted in 4 digits with leading zeros), and the value is a list of students enrolled to that course. - E.g., `"CSCI3920" -> [ stu1, stu2,... ]` - **Clarification**: Only courses with enrolled students will appear in the result. - `remove_student(name)`
