__invert__ — Easy Examples

Defines behavior for the ~ bitwise NOT operator

Implementing __invert__

Basic implementation of __invert__ in a class.

python
class Example:
    def __invert__(self):
        return "Example __invert__"

obj = Example()
print(obj)

__invert__ defines behavior for the ~ bitwise not operator. Implementing it lets you customize how Python interacts with your objects.

__invert__ in action

Seeing __invert__ called by Python's built-in operations.

python
# How Python calls __invert__ automatically
class Demo:
    def __init__(self, value):
        self.value = value

    def __invert__(self):
        print(f"__invert__ was called!")
        return self

d = Demo(42)
# This triggers __invert__:
print(d)

Python automatically calls __invert__ when you use the corresponding operator or function on your object.
