dask.array.less¶
- dask.array.less(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature, extobj]) = <ufunc 'less'>¶
This docstring was copied from numpy.less.
Some inconsistencies with the Dask version may exist.
Return the truth value of (x1 < x2) element-wise.
- Parameters
- x1, x2array_like
Input arrays. If
x1.shape != x2.shape
, they must be broadcastable to a common shape (which becomes the shape of the output).- outndarray, 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.
- wherearray_like, optional
This condition is broadcast over the input. At locations where the condition is True, the out array will be set to the ufunc result. Elsewhere, the out array will retain its original value. Note that if an uninitialized out array is created via the default
out=None
, locations within it where the condition is False will remain uninitialized.- **kwargs
For other keyword-only arguments, see the ufunc docs.
- Returns
- outndarray or scalar
Output array, element-wise comparison of x1 and x2. Typically of type bool, unless
dtype=object
is passed. This is a scalar if both x1 and x2 are scalars.

Examples
>>> np.less([1, 2], [2, 2]) array([ True, False])
The
<
operator can be used as a shorthand fornp.less
on ndarrays.>>> a = np.array([1, 2]) >>> b = np.array([2, 2]) >>> a < b array([ True, False])
