Section 2: The Catalog class Stores a collection of Course objects in a dictionary, hy is the cid of the course, and value is the Course object that corrsponds to the same cid. addCourse(self, cld, cname, credits) Creates a Course object with the punametes and stores it as a valbe in ceuneotferiergs. removeCourse(self, cid]) loadCatalog(self, file) Reads a Consma Separated Values (cw) file with coune infurmutioe and alds its Course object to the courseOferings dictionary. We are not using any libericis so ncad and process the ove file, insicad, yoe will use string methods wo clean the string for probesing ef the cournes. The codle for reading the file has been provided in the staner code add yoe shold not modify it.

Section 3: The Semester class Stores a collection of Course objects for a semester for a student. addCourse(self, course) Adde a Conuree to tha enurses diectionary dropCourse(self, course) Removes a course from this semester. totalCredits(self) A property method (behaves like an attribute) for the total number of credits in this semester. totalCredits(self) isfullTime(self) be considered full-time (tuking 12 er more dedib) or not _ir_(self._repr_(wen) Returns a formatiod sammary of the all the coerses in this semeser. Use the format: eid, ridi cid, .... Settion 4: The L.ean class A class that repesents an amoum of maney, identified by a pecubonodon number. Section 4: The Loan class A class that represents an amount of money, identified by a pseudo-random number. \[ \__{\text {str__ (self), ___repr_(self) }} \] Returns a formatted summary of the loan as a string. Use the format: Balance: Samount \begin{tabular}{|l|l|} \hline Output \\ \hline str & Formatted summary of the loan. \\ \hline \end{tabular} getloanID(self) A property method (behaves like an attribute) that pseudo-randomly generates loan ids. Use the Eindom module to return a number between 10,000 and 99,999 . The retumed value should be saved to loan_id when initializing Loan objects. randint and randrange could be helpful here! Section 6: The Person class This class is a basic representation of a person, storing name and social security number. get_ssn(self) Getter method for aceessing the private social security number attribute. _str__(self),__repr__(self) Returns a formatted summary of the person as a string. The format to use is: Personf name. _eq_(self, other) Determines if two objects are equal. For instances of this class, we will define equality when the SSN of one object is the same as SSN of the other object. You can assume at least one of the objects is a Person object. Section 7: The Staff class This class inherits from the Person class but adds extended functionality for staff members. Attributes, methods, and special methods inherited from Person are not listed in this section. id(self) Property method (behaves like an attribute) for generating staff's id. The format should be: 905 +ininials+last four numbers of ssn. (e.g. 905abc6789). Ignore the security flaws this generation method presents and assume ids are unique. applyHold(self, student) Applies a hold on a student object (set the student's hold attribute to True), removeHold(self, student) Removes a hold on a student object (set the student's hold attribute to False). unenrollStudent(self, student) Unenrolls a student object (set the student's active attribute to False). createStudent(self, person) Creates a Student object from a Person object. The new student should have the same information (namo ten) ac the nersan and alwave starte ant ac a froshman (-Finechman') Section 8: The Student class This class inherits from the Person class and is heavy extended for additional functionality. Attributes, methods, and special methods inherited from Person are not listed in this section. The implementation of Course, Catalog, Semester, Loan and StudentAccount is needed for complete functionality for instances of this class, and you are expected to use methods from some of those classes in this section. This class works in conjunction with other classes, CORRECT FUNCTIONALITY OF THIS CLASS IS WORTH 30% OF YOUR HW GRADE id(self) Property method (behaves like an attribute) for generating student's id. The format should be: initials +last four numbers of ssn (e.g.: abc6789). Ignore the security flaws this generation method presents and assume ids are unique. _ createStudentAccount(self) Creates a StudentAccount object. This should be saved in the account attribute during registerSemester(self) Creates a Semester object and adds it as a value to the semesters dictionary if the student is active and has no holds with key starting at 1 (next key is defined as max(key_value) +1 ), It also updates the student's year attribute according to the number of semesters enrolled. 'Freshman' is a firstyear student (semesters 1 and 2), 'Sophomore' is a second-year student (semesters 3 and 4). 'Junior' is a third-year student (semesters 5 and 6 ) and 'Senior' for any enrollment with more than 6 cemactane enrollCourse(self, cid, catalog) Finds a Course object with the given id from the catalog and adds it to the courses attribute of the Semester object associated with the largest key in the semesters dictionary. Charge the student's account the aporooriate amount of monev. dropCourse(self, cid) Finds a Course object with the given id from the semester associated with the largest key in the semesters dictionary and removes it. When a course is dropped, only half the course cost is refunded to the student's account (cost is based on the current credit price). getLoan(self, amount) If the student is active and currently enrolled full-time (consider the item with the largest key in the semesters dictionary the current enroliment), it creates a Loan object for the student with the given amount, adds it to the student's account's loans dictionary, and uses the amount to make a payment in the student's account. Do NOT remove the line random. seed (1) from the constructor. This ensures replicable pseudo-random number generation across multiple executions, so your loan ids should match the doctest samples. __str_(self),_repr__(self) Returns a formatted summary of the student member as a string. The format to use is: Student(name, id, year)
