# numpy.ma.masked_array.ids

`masked_array.``ids`()

  Return the addresses of the data and mask areas.

  Parameters: | None

  Examples

      >>> x = np.ma.array([1, 2, 3], mask=[0, 1, 1])
      >>> x.ids()
      (166670640, 166659832)

  If the array has no mask, the address of `nomask` is returned. This address is typically not close to the data in memory:

      >>> x = np.ma.array([1, 2, 3])
      >>> x.ids()
      (166691080, 3083169284L)
