Answer:
class Cse20_topic:
def __init__(self, title, length):
self.title = title
self.length = length
def get_length(self):
return self.length
def get_title(self):
return self.title
def get_length_in_days(self):
return self.length*7
def __str__(self):
return f'Title: {self.title}, length: {self.length}'
def __add__(self, other):
return self.length+other.length
Explanation:
The python program above defines the class Cse20 which is used to create a topic ( instance of the Cse20 object). The getter methods like the get_lenght, get_title and get_length_in_days return the length of a topic object, the title of the topic and the topic length in days respectively while the __str__ and __add__ methods overrides the string object and addition of topic length respectively.
