`numpy:array_repr`

Signature

def array_repr(arr, max_line_width = None, precision = None, suppress_small = None)

Return the string representation of an array.

arr : ndarray: Input array.
max_line_width : int, optional: Inserts newlines if text is longer than max_line_width. Defaults to numpy.get_printoptions()['linewidth'].
precision : int, optional: Floating point precision. Defaults to numpy.get_printoptions()['precision'].
suppress_small : bool, 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'].
