In Python, there is no built-in magic method specifically for the bitwise NOT operator (`~`). However, you can achieve similar functionality by defining the `__invert__()` method in your class. The `__invert__()` method is called when the `~` operator is used on an instance of your class. It should return the inverted value of the object. Here's an example of how you can define the `__invert__()` method in a custom class:
1 2 3 4 5 6 7 | class MyClass: def __init__(self, value): self.value = value def __invert__(self): # Perform the inversion operation and return the result return ~self.value |
1 2 3 | obj = MyClass(10) inverted_obj = ~obj print(inverted_obj) # Output: -11 |
Testing if the previous output contains the string __invert__
: True
Testing if the previous output contains the string __inv__
: False

In Python, the tilde (`~`) operator is used for bitwise inversion or negation. The corresponding special method for the tilde operator is `__invert__`. To define the behavior of the tilde operator for a custom class, you can implement the `__invert__` method. Here's an example:
1 2 3 4 5 6 7 | class MyClass: def __init__(self, value): self.value = value def __invert__(self): # Define the behavior of the tilde operator return MyClass(~self.value) |
1 2 3 | obj = MyClass(10) inverted_obj = ~obj print(inverted_obj.value) # Output: -11 |
Testing if the previous output contains the string __invert__
: True
Testing if the previous output contains the string __inv__
: False

In Python, the tilde (`~`) operator is the bitwise NOT operator. It inverts all the bits of its operand. To define the behavior of the tilde operator for a custom class, you need to implement the `__invert__` special method. This method should return the result of applying the bitwise NOT operation to the object. Here's an example:
1 2 3 4 5 6 7 | class MyClass: def __init__(self, value): self.value = value def __invert__(self): # Define the behavior of the ~ operator return ~self.value |
1 2 3 | obj = MyClass(10) result = ~obj print(result) # Output: -11 |
Testing if the previous output contains the string __invert__
: True
Testing if the previous output contains the string __inv__
: False

In Python, there is no special method (`__thing__`) for the bitwise complement operator `~`. The bitwise complement operator is a unary operator that operates on a single value, unlike binary operators like `+` or `*` that operate on two values. The `__add__` method is a special method in Python that defines the behavior for the addition operator (`+`). Similarly, there are other special methods like `__sub__` for subtraction (`-`), `__mul__` for multiplication (`*`), and so on. However, for the bitwise complement operator (`~`), there is no corresponding special method in Python. The operator is applied directly to the value using the built-in functionality of the language. Here's an example to illustrate the usage of the bitwise complement operator:
1 2 3 4 | x = 5 # Binary: 0101 result = ~x print(result) # Output: -6 |
Testing if the previous output contains the string __invert__
: False
Testing if the previous output contains the string __inv__
: False

In Python, there is no special method or magic method for the bitwise NOT operator (`~`), unlike the `__add__` method for the `+` operator. The bitwise NOT operator (`~`) is a unary operator that performs a bitwise inversion on the operand. It flips all the bits of the operand, converting 0s to 1s and 1s to 0s. The result is the one's complement of the operand. Here's an example of using the bitwise NOT operator:
1 2 3 | x = 5 # Binary: 0101 result = ~x print(result) # Output: -6 |
