less(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'less'>¶
Return the truth value of (x1 < x2) element-wise.
- x1, x2 : array_like
Input arrays. If
x1.shape != x2.shape, they must be broadcastable to a common shape (which may be the shape of one or the other).
- 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.
- out : ndarray or scalar
Output array, element-wise comparison of x1 and x2. Typically of type bool, unless
dtype=objectis passed. This is a scalar if both x1 and x2 are scalars.
