Question

class Student:
def _init_(self, firstname, lastname, idnum):
self.first = firstname
self.last = lastname
self.id = idnum
self.courses = []
def add_course(self, course):
''' don't allow overloads or signing up for the same course twice
if course not in self.courses and len(self.courses) < 5:
self.courses.append (course)
def clear_courses(self):
''clear this student's course schedule''"
self.courses = []
def overload (self):
return len(self.courses) >= 4
What are all of the attributes of this class?
last
overload
idnum
add_course
self
first
course
firstname
courses
id
clear_courses
lastname

Suppose that we wanted to add support for comparison between Student objects in order to sort based on name.
Which of the following methods would be the correct way to write support for the less than operator?
def _lt_(self, other):
if self.last < other.last:
return True
elif self.last == other.last:
return self.first < other.first
else:
return False
def_lt_(self):
return self.last < other.last
def
_lt_(self, student2):
if last < student2.last:
return True
else:
return False
def _lt__(self, other):
if self.last < other.last and self.first < other.first:
return True
else:
return False
def _lt_(self, other):
return self < other

Expert Solution

Step 1

The program in question 1 is based on OOPs (Object Oriented Programming) concept. In which different methods along with different attributes are available under class Student.

In question 2 we need to find out the correct option according to the requirement given in the question i.e. to add support for comparison between Student objects in order to sort based on the name.
