Question

1. Write a constructor for a class called Book that will have a title, author, and price.
2. Describe why the following code might be frustrating to the player of the game and how you might change it.

while self.doorlocked == True:
response = input("Enter the escape code.")
if (response == doorCombo):
print("You have escaped!")
self.doorlocked = False

Write code that will randomly output one of four phrases to a student who has gotten a correct answer on a quiz.
3. Imagine that you are creating a program that an online streaming service will use to manage its inventory of shows. 4. Describe at least two classes that you would create and several subclasses.
5. Describe what information should be in the comments at the top of a program file and why that information would be helpful.

Answer 1

Here are the answers to your questions:

1. Constructor for the Book Class

class Book:
    def __init__(self, title, author, price):
        self.title = title
        self.author = author
        self.price = price

2. Code Frustration Explanation

The provided code snippet can be frustrating for a player for several reasons:

1. No Feedback Before Input: The player has to input the escape code without knowing if they're anywhere close to the correct answer. If they enter an incorrect code, they receive no information on what was wrong, leading to repeated trial and error without any strategy on their part.

2. Lack of Opportunities to Escape: If the player fails, they may become stuck in an infinite loop, having to guess the code without any hints.

3. Missed Opportunities for Engagement: The game could be more engaging by providing hints or clues after a certain number of failed attempts.

To improve this, you could implement the following changes:

attempts = 0
max_attempts = 3
correct_code = "1234"  # Example code

while self.doorlocked:
    response = input("Enter the escape code (Attempt {}/{}): ".format(attempts + 1, max_attempts))
    
    if response == correct_code:
        print("You have escaped!")
        self.doorlocked = False
    else:
        attempts += 1
        print("Incorrect code. Try again.")
        if attempts >= max_attempts:
            print("You've used all your attempts. The door remains locked.")
            break

3. Classes for Online Streaming Service Inventory

Main Classes

• Show

  • Attributes: title, genre, release year, duration, rating
  • Methods: add_to_inventory(), remove_from_inventory()

• User

  • Attributes: username, subscription type (free, basic, premium), watch history
  • Methods: subscribe(), unsubscribe(), view_show()

Subclasses

• Movie (subclass of Show)

  • Additional Attribute: director
  • Additional Method: mark_as_favorite()

• Series (subclass of Show)

  • Additional Attribute: number of seasons
  • Additional Method: add_episode()

By creating these classes and their subclasses, the streaming service can effectively manage the content they offer and the user interactions with that content.

4. Comments at the Top of a Program File

At the top of a program file, the following information should be included in the comments:

"""
Program Name: Streaming Inventory Management System
Author: Your Name
Date Created: YYYY-MM-DD
Description: This program manages the inventory of shows for an online streaming service, including functionalities for adding, removing, and viewing shows as well as user management.
Version: 1.0
"""

Why This Information is Helpful:

• Program Name: Quickly identifies what the program is for without needing to read through the entire code.
• Author: Gives credit and allows for follow-up questions or clarifications by the author.
• Date Created: Provides context for how current the program is, which can be helpful in ongoing projects.
• Description: Offers a summary that helps anyone reading the code (including future you) to understand its purpose and functionality without diving deeply into the logic.
• Version: Tracks changes and updates over time, which is critical in collaborative projects or when revisiting the program later.

These comments aid in maintainability and facilitate collaboration among developers, making the codebase easier to understand and work with.
