`numpy.lib._iotools:flatten_dtype`

source: build-install/usr/lib/python3.14/site-packages/numpy/lib/_iotools.py:85

Signature

def flatten_dtype(ndtype, flatten_base = False)

Summary

Unpack a structured data-type by collapsing nested fields and/or fields with a shape.

Extended Summary

Note that the field names are lost.

Parameters

ndtype : dtype: The datatype to collapse
flatten_base : bool, optional: If True, transform a field with a shape into several fields. Default is False.

Examples

import numpy as np
dt = np.dtype([('name', 'S4'), ('x', float), ('y', float),
               ('block', int, (2, 3))])
np.lib._iotools.flatten_dtype(dt)

✓

[dtype('S4'), dtype('float64'), dtype('float64'), dtype('int64')]

np.lib._iotools.flatten_dtype(dt, flatten_base=True)

✗

[dtype('S4'), dtype('float64'), dtype('float64'), dtype('int64'), dtype('int64'), dtype('int64'), dtype('int64'), dtype('int64'), dtype('int64')]
