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 :
# Python program explaining # numpy.char.rstrip() method   import numpy as geek   # input arrays  in_arr = geek.array(['Sun', ' Moon ', 'Star']) print ("Input array : ", in_arr)   out_arr = geek.char.rstrip(in_arr)   # whitespace removed from arr[1] # as we have set chars = None print ("Output array: ", out_arr) |
Output:
Input array : ['Sun' ' Moon ' 'Star'] Output array: ['Sun' 'Moon' 'Star']
Â
Code #2 :
# Python program explaining # numpy.char.rstrip() method   import numpy as geek   # input arrays in_arr = geek.array([ 'Geeks', 'For', 'Geeks'] ) print ("Input array : ", in_arr)   out_arr = geek.char.rstrip(in_arr, chars ='s')   #'s' removed from arr[0] and # arr[2] as we have set chars ='s' print ("Output array: ", out_arr) |
Output:
Input array : ['Geeks' 'For' 'Geeks'] Output array: ['Geek' 'For' 'Geek']

Code #3 :
# Python program explaining # numpy.char.rstrip() method   import numpy as geek   # input arrays in_arr = geek.array([ 'GeeksG', 'ForG', 'Geeks'] ) print ("Input array : ", in_arr)   out_arr = geek.char.rstrip(in_arr, chars ='G')   # will strip 'G' from right side # from each element(if exists) print ("Output array: ", out_arr) |
Output:
Input array : ['GeeksG' 'ForG' 'Geeks'] Output array: ['Geeks' 'For' 'Geeks']
