Question
Assuming that we have defined the Card class as above, fill in the blank in the code below such that the code segment prints out "Yes" without causing any errors.

```python
if ________ > Card('Queen', 'Spades'):
    print("Yes")
```

In this task, you need to replace the blank space with an appropriate expression so that the conditional statement evaluates to true and prints "Yes". This involves understanding the comparison logic provided by the `Card` class.
Transcribed Image Text:Assuming that we have defined the Card class as above, fill in the blank in the code below such that the code segment prints out "Yes" without causing any errors. ```python if ________ > Card('Queen', 'Spades'): print("Yes") ``` In this task, you need to replace the blank space with an appropriate expression so that the conditional statement evaluates to true and prints "Yes". This involves understanding the comparison logic provided by the `Card` class.
The code snippet below demonstrates the implementation of a `Card` class in Python, which assigns ranks to card values using a dictionary.

```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):**
    - The `Card` class is initialized with `value` and `suit` parameters.
    - A dictionary named `order` maps card names to their corresponding ranks.
    - The `rank` attribute is assigned based on the card's value using this dictionary.

2. **String Representation (`__repr__` method):**
    - Provides a string representation for the card instance in the format `"value of suit"`.

3. **Greater Than Method (`__gt__` method):**
    - Compares two card instances.
    - It returns `True` if the card's rank is greater than another card's rank and the card's suit is `'Hearts'`.

This class can be used to compare cards, print them, and categorize them by rank and suit.
