numpy.array_repr() in Python

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.

# Python program explaining
# array_repr() function

import numpy as geek
arr = geek.array([4, -8, 7 ])

print ("Input  array : ", arr)
print(type(arr))
  
out_arr = geek.array_repr(arr)
print ("The string representation of input array : ", out_arr) 
print(type(out_arr))

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

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'
