Class Range

          |    
??.instance --+
              |
             Range


Property 'ndarray' provides a numpy.ndarray view on the object.
If you create a reference to 'ndarray', you must keep the object unchanged until your reference is deleted, or Python may crash!

To create an instance of Range that shares the same data with an ndarray instance, use:
    'Range.from_ndarray(a)' or 'asRange(a)
where 'a' is an ndarray instance. Similarly, to avoid a potential Python crash, you must keep the current instance unchanged until the reference is deleted.
