cf.wi(value0, value1, units=None, attr=None)[source]

A Query object for a “within a range” condition.

If units is specified and the already value has units (such as a Data object), then they must be equivalent. attr: str, optional Apply the condition to the attribute, or nested attributes, of the operand, rather than the operand itself. Nested attributes are specified by separating them with a .. For example, the “month” attribute of the “bounds” attribute is specified as 'bounds.month'. Query The query object.

>>> q = cf.wi(5, 7)
>>> q
<CF Query: wi (5, 7)>
>>> q.evaluate(6)
True
>>> q.evaluate(4)
False
