NumPy: rpartition() function

numpy.core.defchararray.rpartition() function

The numpy.core.defchararray.rpartition() function is used to partition (split) each element around the right-most separator.
Calls str.rpartition element-wise.
For each element in a, 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.

Version: 1.15.0

Syntax:

numpy.core.defchararray.rpartition(a, sep)

Parameter:

Return value:

out : ndarray - Output array of string or unicode, depending on input type. The output array will have an extra dimension with 3 elements per input element.

Some methods will only be available if the corresponding string method is available in your version of Python.

The preferred alias for 'defchararray' is 'numpy.char'.

Example-1: numpy.rpartition() function

import numpy as np
x = "Python Exercises, Practice, Solution"
print("Original string:")
print(x)
print("\nHere separator is 'Practice'")
print(np.char.rpartition(x, 'Practice'))
print("\nHere separator is 'Solution'")
print(np.char.rpartition(x, 'Solution'))
print("\nHere separator is ','")
print(np.char.rpartition(x, ','))

Output:

Original string:
Python Exercises, Practice, Solution

Here separator is 'Practice'
['Python Exercises, ' 'Practice' ', Solution']

Here separator is 'Solution'
['Python Exercises, Practice, ' 'Solution' '']

Here separator is ','
['Python Exercises, Practice' ',' ' Solution']

Example-2: numpy.rpartition() function

import numpy as np
x = "Python Exercises, Solution,  Practice, Solution"
print("Original string:")
print(x)
print("\nHere separator is 'Solution'")
print(np.char.rpartition(x, 'Solution'))

Output:

Original string:
