In Python, operator overloading allows you to define or customize the behavior of operators (`+`, `-`, `~`, etc.) for your own classes by implementing special methods. For the bitwise NOT operator `~`, the corresponding special method is `__invert__`. ### Using `__invert__` with the `~` Operator Here's how you can use the `__invert__` method in a custom class:

class MyNumber:
    def __init__(self, value):
        self.value = value

    def __invert__(self):
        # Implement the bitwise NOT operation
        return MyNumber(~self.value)

    def __repr__(self):
        return f"MyNumber({self.value})"

# Example usage
num = MyNumber(10)      # Binary: 1010
inverted = ~num        # Should perform bitwise NOT

print(inverted)        # Output: MyNumber(-11)
### Explanation: 1. **Defining the Class:** - `MyNumber` is a custom class that holds an integer value. 2. **Implementing `__invert__`:** - The `__invert__` method is defined to handle the `~` operator. - It applies Python's built-in `~` operator to `self.value` and returns a new instance of `MyNumber` with the inverted value. 3. **Using the `~` Operator:** - When you apply `~` to an instance of `MyNumber`, Python internally calls the `__invert__` method. - For example, `~MyNumber(10)` will compute `~10`, which is `-11` in Python due to two's complement representation of integers. 4. **Representation:** - The `__repr__` method is overridden to provide a readable string representation of the `MyNumber` instances, which is helpful for debugging and display purposes. ### Additional Operator Overloads Here are a few more special methods corresponding to other operators: | Operator | Special Method | |----------|---------------------| | `+` | `__add__(self, other)` | | `-` | `__sub__(self, other)` | | `*` | `__mul__(self, other)` | | `/` | `__truediv__(self, other)` | | `//` | `__floordiv__(self, other)` | | `%` | `__mod__(self, other)` | | `**` | `__pow__(self, other)` | | `<<` | `__lshift__(self, other)` | | `>>` | `__rshift__(self, other)` | | `&` | `__and__(self, other)` | | `|` | `__or__(self, other)` | | `^` | `__xor__(self, other)` | | `~` | `__invert__(self)` | Implementing these methods allows your custom classes to interact with Python’s operators seamlessly, enhancing their functionality and integration with other parts of your code. ### Final Note When overloading operators, it's essential to ensure that the behavior remains intuitive and consistent with the expected use of the operator to maintain code readability and prevent unexpected behaviors.

Output

In Python, the `~` operator corresponds to the `__invert__` special method. This method allows you to define custom behavior for the bitwise NOT operation when using the `~` operator with instances of your classes. ### Example:

class BitwiseInvertible:
    def __init__(self, value):
        self.value = value

    def __invert__(self):
        # Define custom behavior for the ~ operator
        return BitwiseInvertible(~self.value)

    def __repr__(self):
        return f"BitwiseInvertible({self.value})"

# Usage
num = BitwiseInvertible(10)  # Binary: 1010
print(num)                    # Output: BitwiseInvertible(10)

inverted_num = ~num
print(inverted_num)           # Output: BitwiseInvertible(-11)
### Explanation: 1. **Defining `__invert__`**: - The `__invert__` method is called when the `~` operator is used. - In the example, applying `~` to an instance of `BitwiseInvertible` creates a new instance with the inverted value. 2. **Using the `~` Operator**: - `~num` invokes `num.__invert__()`, which returns a new `BitwiseInvertible` instance with the inverted value. 3. **Output**: - The original number `10` is represented as `BitwiseInvertible(10)`. - After inversion, it becomes `BitwiseInvertible(-11)`, since `~10` inverts the bits of `10`, resulting in `-11` in two's complement representation. ### Reference: - [Python Data Model - Emulating Container Types](https://docs.python.org/3/reference/datamodel.html#emulating-container-types) ### Summary: To customize the behavior of the `~` operator in your Python classes, implement the `__invert__` method. This allows instances of your class to respond appropriately when the `~` operator is used. --- Feel free to ask if you have more questions about operator overloading or Python's special methods!
