# numpy.dtype.subdtype

attribute

dtype.subdtype

  Tuple `(item_dtype, shape)` if this `dtype` describes a sub-array, and None otherwise.

  The shape is the fixed shape of the sub-array described by this data type, and item_dtype the data type of the array.

  If a field whose dtype object has this attribute is retrieved, then the extra dimensions implied by shape are tacked on to the end of the retrieved array.

  Examples

      >>> x = numpy.dtype('8f')
      >>> x.subdtype
      (dtype('float32'), (8,))

      >>> x =  numpy.dtype('i2')
      >>> x.subdtype
      >>>
