NumPy String: numpy.char.rsplit() function

numpy.char.rsplit() function

For each element in a given array the numpy.char.rsplit() function returns a list of the words in the string, using separator as the delimiter string, working from the end of the string towards the beginning.
The function is useful for splitting file paths or filename.

Syntax:

numpy.char.rsplit(a, sep=None, maxsplit=None)

Parameters:

Return value:

out : ndarray - Array of list objects

Example: Using numpy.char.rsplit() to split a string at specified separator

>>> import numpy as np
>>> x = np.char.rsplit('w3resource', ':', maxsplit=None)
>>> x
array(list(['w3resource']), dtype=object)

In the above code, the string 'w3resource' is split using ':' as the separator. Since ':' is not present in the string, the original string is returned as a list with one element. The maxsplit parameter is set to None, indicating that the split should continue until there are no more separators in the string.

Example: Splitting a string using numpy.char.rsplit()

>>> import numpy as np
>>> y = np.char.rsplit('hello world', ':', maxsplit=11)
>>> y
array(list(['hello world']), dtype=object)

In the above case, the string "hello world" is split using the delimiter ":". Since there are no instances of the delimiter in the string, the function returns an array with a single element, which is the original string "hello world". The maxsplit parameter is set to 11, which means that the string is split at most 11 times. Since there is only one element in the string, this parameter has no effect in this case
