numpy.array_repr() in Python

0 0 1 minute read

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.

Code #1 : Working

# 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)) 

Output :

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

Code #2 : Working

# Python program explaining 
# array_repr() function 
  
import numpy as geek 
in_arr = geek.array([5e-8, 4e-7, 8, -4]) 
  
print ("Input  array : ", in_arr) 
print(type(in_arr)) 
    
out_arr = geek.array_repr(in_arr, precision = 6, suppress_small = True) 
print ("The string representation of input array : ", out_arr)  
print(type(out_arr)) 

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'
