strings.less(x1, x2, /, out=None, *, where=True, casting='same_kind', order='K', dtype=None, subok=True[, signature])=<ufunc'less'>
Return the truth value of (x1 < x2) element-wise.
Parameters:x1, x2array_likeInput 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, optionalA 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, optionalThis 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.
**kwargsFor other keyword-only arguments, see the
.
Returns:outndarray or scalarOutput array, element-wise comparison of x1 and x2. Typically of type bool, unless dtype=np.object_ is passed. This is a scalar if both x1 and x2 are scalars.
Examples
>>> importnumpyasnp>>> np.less([1,2],[2,2])array([ True, False])The < operator can be used as a shorthand for np.less on ndarrays.
>>> a=np.array([1,2])>>> b=np.array([2,2])>>> a<barray([ True, False])
