numpy.char.rpartition

char.rpartition(a, sep)

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.

Parameters:

aarray-like, with StringDType, bytes_, or str_ dtype

Input array

sepstr or unicode

Right-most separator to split each element in array.

Returns:

outndarray

Output array of StringDType, bytes_ or str_ dtype, depending on input types. The output array will have an extra dimension with 3 elements per input element.
