Numpy string operations | rpartition() function

In the numpy.core.defchararray.rpartition() function,  each element in arr, split the element as the last occurrence of sep, and return 3 strings containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, return 3 strings containing the string itself, followed by two empty strings.

Syntax : numpy.core.defchararray.rpartition(arr, sep)

Parameters :

arr : [array_like, {str, unicode}]  Given Input array.

sep : [str or unicode] Right-most separator to split each element in array.

Return : [ndarray] Return the output array of str or unicode, depending on input type

Code #1 :  

# Python program explaining 
# numpy.char.rpartition() function 
# importing numpy as geek  
import numpy as geek 
arr = "GeeksforGeeks - A computer science portal for geeks"
sep = 'None'
gfg = geek.char.rpartition(arr, sep)
  
print (gfg)

Output :  

['' '' 'GeeksforGeeks - A computer science portal for geeks']

Code #2 :  

# Python program explaining 
# numpy.char.rpartition() function 
# importing numpy as geek  
import numpy as geek 
arr = "GeeksforGeeks - A computer science portal for geeks"
sep = 'science'
gfg = geek.char.rpartition(arr, sep)
  
print (gfg)

Output : 

['GeeksforGeeks - A computer ' 'science' ' portal for geeks']
