operator.inv

bitwise

An alias of operator.invert: bitwise inversion ~a.

Syntax

operator.inv(a)

The documentation describes inv and invert together: two names for the one ~ operation. They are separate objects with identical behaviour, not one function under two names, so inv is invert is False. New code should prefer invert, whose name matches the special method __invert__.

Examples

import operator
print(operator.inv(5))   # → -6
print(operator.inv(5) == ~5)   # → True
print(operator.inv(5) == operator.invert(5))   # → True
print(list(map(operator.inv, [0, 1, -1])))   # → [-1, -2, 0]
print(operator.inv(2.0))   # → TypeError
