numpy.strings.rpartition#

strings.rpartition(a, sep)[source]#

Partition (split) each element around the right-most separator.

For each element in a, split the element at the last occurrence of sep, and return a 3-tuple containing the part before the separator, the separator itself, and the part after the separator. If the separator is not found, the third item of the tuple will contain the whole string, and the first and second ones will be the empty string.

Parameters:

aarray-like, with StringDType, bytes_, or str_ dtype: Input array
separray-like, with StringDType, bytes_, or str_ dtype: Separator to split each string element in a.

Returns:

out3-tuple:

array with StringDType, bytes_ or str_ dtype with the part before the separator
array with StringDType, bytes_ or str_ dtype with the separator
array with StringDType, bytes_ or str_ dtype with the part after the separator
