numpy.dtype.subdtype — NumPy v2.2 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

import numpy as np x = numpy.dtype('8f') x.subdtype (dtype('float32'), (8,))

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