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.
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'
