numpy.logical_not(x[, out]) = <ufunc 'logical_not'>

Compute the truth value of NOT x element-wise.

Parameters:

x : array_like

Logical NOT is applied to the elements of x.

Returns:

y : bool or ndarray of bool

Boolean result with the same shape as x of the NOT operation on elements of x.

Examples

>>> np.logical_not(3)
False
>>> np.logical_not([True, False, 0, 1])
array([False,  True,  True, False], dtype=bool)
>>> x = np.arange(5)
>>> np.logical_not(x<3)
array([False, False, False,  True,  True], dtype=bool)
