numpy.array_repr() in Python

numpy.array_repr()function is used to convert an array to a string.

Syntax : numpy.array_repr(arr, max_line_width=None, precision=None, suppress_small=None)

Parameters :
arr : [array_like] Input array.
max_line_width : [int, optional] The maximum number of columns the string should span. Newline characters split the string appropriately after array elements.
precision : [int, optional] Floating point precision. Default is the current printing precision (generally 8).
suppress_small : [bool, optional] It represent very small numbers as zero, default is False. Very small number is defined by precision, if the precision is 8 then numbers smaller than 5e-9 are represented as zero.



Return : [str] The string representation of an array.
