Question

Write the implementation of a class Cse20 Topic that represents a topic in the cse20 class. The class should implement the init function, getters, and override the str and add functions.

Answer 1

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.
