Read the following code then check all the statements that are true concerning the code. class Date ( ):         def __init__ (self, month, day, year):                 self.__month = month                 self.__day = day                 self.__year = year Assume code that uses the above class has created a Date object and assigned it variable id d1.

An object is a specific instance of a class whose attribute values can be different from other objects of that class.

View the following class definition, then answer the question that follows. class Date ( ):       def __init__ (self, month, day, year, descr):                 self.month = month                 self. day = day self.year = year                self.descr = descr         def __str__ (self):                 return str(self.month) + ‘/’ + str(self.day) + ‘/’ + str(self.year) + ‘ – ‘ + self.descrd1 = Date(’08’, ’26’, ‘2024’, ‘Start of semester’) Which of the following will reset the year of the above object to 2025? 

Write the exact outcome of the following code. class Point(object):     def __init__(self, x, y):         self.x = x         self.y = y             def equal(self, other):         if self.x == other.x and self.y == other.y:             return True         else:             return False p1 = Point(4,2) p2 = Point(4,10) print(p1.equal(p2)) #outcome of this line

Method overriding needs a super() function call.

Inheritance is a way to reuse already written code. 

Which of the following is false about inheritance?
