numpy.array_str()function is used to represent the data of an array as a string.
The data in the array is returned as a single string. This function is similar to array_repr, the difference being that array_repr also returns information on the kind of array and its data type.
Syntax : numpy.array_str(arr, max_line_width=None, precision=None, suppress_small=None)
arr : [array_like] Input array.
max_line_width : [int, optional] Inserts newlines if text is longer than max_line_width. The default is, indirectly, 75.
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.
Code #1 : Working
Input array : [ 4 -8 7] class 'numpy.ndarray' The string representation of input array : array([ 4, -8, 7]) class 'str'
Code #2 : Working
Input array : [ 5.00000000e-08 4.00000000e-07 8.00000000e+00 -4.00000000e+00] class 'numpy.ndarray' The string representation of input array : array([ 0., 0., 8., -4.]) class 'str'
