numpy.array_str() in Python

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) Parameters : 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 Output :

Input array : [ 4 -8 7]
class 'numpy.ndarray'
The string representation of input array : array([ 4, -8, 7])
class 'str'

  Code #2 : Working

Output :

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'
