numpy string operations | rstrip() function (original) (raw)

Last Updated : 17 Jan, 2019

numpy.core.defchararray.rstrip(arr, chars=None) is another function for doing string operations in numpy. It returns a copy with the trailing characters removed for each element in arr.

Parameters:
arr : array_like of str or unicode.
char : [str or unicode, optional] the set of characters to be removed. If omitted or None, it removes whitespace. The chars argument is not a prefix or suffix; it is all combinations of its values which we want to strip.

Returns : [ndarray] Output array of str or unicode, depending on input type.

Code #1 :

import numpy as geek

in_arr = geek.array([ 'Sun' , ' Moon ' , 'Star' ])

print ( "Input array : " , in_arr)

out_arr = geek.char.rstrip(in_arr)

print ( "Output array: " , out_arr)

Output:

Input array : ['Sun' ' Moon ' 'Star'] Output array: ['Sun' 'Moon' 'Star']

Code #2 :

import numpy as geek

in_arr = geek.array([ 'Geeks' , 'For' , 'Geeks' ] )

print ( "Input array : " , in_arr)

out_arr = geek.char.rstrip(in_arr, chars = 's' )

print ( "Output array: " , out_arr)

Output:

Input array : ['Geeks' 'For' 'Geeks'] Output array: ['Geek' 'For' 'Geek']

Code #3 :

import numpy as geek

in_arr = geek.array([ 'GeeksG' , 'ForG' , 'Geeks' ] )

print ( "Input array : " , in_arr)

out_arr = geek.char.rstrip(in_arr, chars = 'G' )

print ( "Output array: " , out_arr)

Output:

Input array : ['GeeksG' 'ForG' 'Geeks'] Output array: ['Geeks' 'For' 'Geeks']
