Python

The code snippet below defines a class `Card` useful for representing and comparing playing cards. Each card has a `value` (e.g., "Ace", "Two", "Three", etc.) and a `suit` (e.g., "Hearts", "Diamonds"). Here's a detailed breakdown of the code functionality: ```python class Card: def __init__(self, value, suit): self.value = value self.suit = suit order = {'Ace': 1, 'Two': 2, 'Three': 3, 'Four': 4, 'Five': 5, 'Six': 6, 'Seven': 7, 'Eight': 8, 'Nine': 9, 'Ten': 10, 'Jack': 11, 'Queen': 12, 'King': 13} self.rank = order[self.value] def __repr__(self): return self.value + ' of ' + self.suit def __gt__(self, other): return self.rank > other.rank and self.suit == 'Hearts' ``` ### Explanation: 1. **Class Initialization (`__init__` method):** - **Parameters:** The constructor takes `value` and `suit` as parameters to initialize a card. - **Order Dictionary:** A dictionary named `order` assigns a numerical rank to each card value. This is used to compare cards by rank. - **Rank Assignment:** `self.rank` is set according to the card's `value` using the dictionary. 2. **String Representation (`__repr__` method):** - Returns a string in the format of "Value of Suit", allowing easy printing of a card object (e.g., "Ace of Hearts"). 3. **Greater-Than Comparison (`__gt__` method):** - Compares two cards by their rank, but considers a card greater if it's rank is higher and it's a Heart. This class provides a simple model for working with a deck of cards, allowing for representation and rudimentary comparison based on rank and suit.

**Task Description:** List all of the methods of the Card class, and for each one, write what type (string, int, None, etc.) the method returns. You don't need to include the constructor method (__init__). **Instructions:** - Identify all methods within the Card class, excluding the constructor (`__init__`). - Provide the return type for each method, such as string, int, None, etc. This task is aimed at understanding object-oriented programming concepts, specifically focusing on methods and return types within a class structure.
