numpy.logical_not — NumPy v1.11 Manual (original) (raw)
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. |
|---|---|

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)
