numpy.char.chararray.size — NumPy v2.2 Manual (original) (raw)

attribute

char.chararray.size#

Number of elements in the array.

Equal to np.prod(a.shape), i.e., the product of the array’s dimensions.

Notes

a.size returns a standard arbitrary precision Python integer. This may not be the case with other methods of obtaining the same value (like the suggested np.prod(a.shape), which returns an instance of np.int_), and may be relevant if the value is used further in calculations that may overflow a fixed size integer type.

Examples

import numpy as np x = np.zeros((3, 5, 2), dtype=np.complex128) x.size 30 np.prod(x.shape) 30
