numpy.ndarray.dtype

attribute

ndarray.dtype

Data-type of the array’s elements.

Setting arr.dtype is discouraged and may be deprecated in the future. Setting will replace the dtype without modifying the memory (see also ndarray.view and ndarray.astype).

Parameters:

None

Returns:

dnumpy dtype object

See also

ndarray.astype

Cast the values contained in the array to a new data-type.

ndarray.view

Create a view of the same data but a different data-type.

Examples

>>> import numpy as np
>>> x = np.arange(4).reshape((2, 2))
>>> x
array([[0, 1],
       [2, 3]])
>>> x.dtype
dtype('int64')   # may vary (OS, bitness)
>>> isinstance(x.dtype, np.dtype)
True
