numpy.dtype.subdtype — NumPy v1.18 Manual (original) (raw)

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
