logical_and(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'logical_and'>¶
Compute the truth value of x1 AND x2 element-wise.
- x1, x2 : array_like
Input arrays. x1 and x2 must be of the same shape.
- out : ndarray, None, or tuple of ndarray and None, optional
A location into which the result is stored. If provided, it must have a shape that the inputs broadcast to. If not provided or None, a freshly-allocated array is returned. A tuple (possible only as a keyword argument) must have length equal to the number of outputs.
- where : array_like, optional
Values of True indicate to calculate the ufunc at that position, values of False indicate to leave the value in the output alone.
For other keyword-only arguments, see the ufunc docs.
- y : ndarray or bool
Boolean result with the same shape as x1 and x2 of the logical AND operation on corresponding elements of x1 and x2. This is a scalar if both x1 and x2 are scalars.
>>> np.logical_and(True, False) False >>> np.logical_and([True, False], [False, False]) array([False, False])
>>> x = np.arange(5) >>> np.logical_and(x>1, x<4) array([False, False, True, True, False])
