Question

How would I setup this dictionary for Python 3?

class Student(object):

def __init__(self, id, firstName, lastName, courses = None):

The “id”, “firstName” and “lastName” parameters are to be directly assigned to member variables (ie: self.id = id)

The “courses” parameter is handled differently. If it is None, assign dict() to self.courses, otherwise assign courses directly to the member variable.

Note: The “courses” dictionary contains key/value pairs where the key is a string that is the course number (like “course1”) and the value is a number from 0-4.0 (represents the grade the student received).

Example of the input:

123456, John, Wick, 'Course1': 3.50, 'Course2': 3.00, 'Course21': 4.00, 'Course22': 3.75, 'Course25': 4.00

Answer 1

class Student(object):
    def __init__(self, id, firstName, lastName, courses = None):
        self.id = id
        self.firstName = firstName
        self.lastName = lastName
        
        if courses is None:
            self.courses = dict()
        else:
            self.courses = courses

    def printMe(self):
        print(self.id)
        print(self.firstName)
        print(self.lastName)
        print(self.courses)


stud = Student(123456, 'John', 'Wick', {'Course1': 3.50})
stud.printMe()
