The image presents a coding exercise on an educational website. It asks the reader to identify the rich comparison method in the given Python class.### Code Explanation:```pythonclass SumofPairs: num3 = 5 def __init__(self, num1, num2): self.num1 = num1 self.num2 = num2 def __str__(self): return '{} {}'.format(self.num1, self.num2) def __add__(self, other): num1 = self.num1 + other.num1 num2 = self.num2 + other.num2 return SumofPairs(num1, num2)```- **Class Definition**: `SumofPairs` is a class with an attribute `num3` set to 5.- **Constructor (`__init__`)**: Initializes two instance variables, `num1` and `num2`.- **String Representation (`__str__`)**: Returns a formatted string representation of the instance variables.- **Addition Method (`__add__`)**: Defines addition for `SumofPairs` objects, allowing the addition of two instances and returning a new `SumofPairs` object with summed values.### Multiple Choice Options:- `__add__`- `__init__`- `__str__`- `num3`The task is to identify the rich comparison method among the options. Note that rich comparison methods facilitate object comparisons using operators like `<`, `<=`, `>`, `>=`, `==`, and `!=`. The provided code, however, does not include a rich comparison method, as `__add__`, `__init__`, `__str__`, and `num3` do not perform any comparison operations.

Answer:- _add_Rich comparison means here the add operator is overloaded to add the objects of the class. So this type of comparison where is the operator is overloaded to compare objects are called rich comparisons.

Given the class below, identify the rich comparison method. class SumofPairs: num3 = 5 def _init_(self, num1, num2): self.num1 = num1 self.num2 = num2 def _str_(self): return('{} {}'.format(self.num1, self.num2)) def _add_(self, other): num1 = self.num1 + other.num1 num2 = self.num2 + other.num2 return SumofPairs(num1, num2)

Given the class below, identify the rich comparison method. class SumofPairs: num3 = 5 def _init_(self, num1, num2): self.num1 = num1 self.num2 = num2 def _str_(self): return('{} {}'.format(self.num1, self.num2)) def _add_(self, other): num1 = self.num1 + other.num1 num2 = self.num2 + other.num2 return SumofPairs(num1, num2)

Question

The image presents a coding exercise on an educational website. It asks the reader to identify the rich comparison method in the given Python class.

### Code Explanation:

```python
class SumofPairs:
num3 = 5

def __init__(self, num1, num2):
self.num1 = num1
self.num2 = num2

def __str__(self):
return '{} {}'.format(self.num1, self.num2)

def __add__(self, other):
num1 = self.num1 + other.num1
num2 = self.num2 + other.num2
return SumofPairs(num1, num2)
```

- **Class Definition**: `SumofPairs` is a class with an attribute `num3` set to 5.
- **Constructor (`__init__`)**: Initializes two instance variables, `num1` and `num2`.
- **String Representation (`__str__`)**: Returns a formatted string representation of the instance variables.
- **Addition Method (`__add__`)**: Defines addition for `SumofPairs` objects, allowing the addition of two instances and returning a new `SumofPairs` object with summed values.

### Multiple Choice Options:

- `__add__`
- `__init__`
- `__str__`
- `num3`

The task is to identify the rich comparison method among the options. Note that rich comparison methods facilitate object comparisons using operators like `<`, `<=`, `>`, `>=`, `==`, and `!=`. The provided code, however, does not include a rich comparison method, as `__add__`, `__init__`, `__str__`, and `num3` do not perform any comparison operations.
