numpy.array_repr — NumPy v2.3 Manual (original) (raw)

numpy.array_repr(arr, max_line_width=None, precision=None, suppress_small=None)[source]#

Return the string representation of an array.

Parameters:

arrndarray

Input array.

max_line_widthint, optional

Inserts newlines if text is longer than max_line_width. Defaults to numpy.get_printoptions()['linewidth'].

precisionint, optional

Floating point precision. Defaults to numpy.get_printoptions()['precision'].

suppress_smallbool, optional

Represent numbers “very close” to zero as zero; default is False. Very close is defined by precision: if the precision is 8, e.g., numbers smaller (in absolute value) than 5e-9 are represented as zero. Defaults to numpy.get_printoptions()['suppress'].

Returns:

stringstr

The string representation of an array.

Examples

import numpy as np np.array_repr(np.array([1,2])) 'array([1, 2])' np.array_repr(np.ma.array([0.])) 'MaskedArray([0.])' np.array_repr(np.array([], np.int32)) 'array([], dtype=int32)'

x = np.array([1e-6, 4e-7, 2, 3]) np.array_repr(x, precision=6, suppress_small=True) 'array([0.000001, 0. , 2. , 3. ])'
