str.
rindex
(sub, start=0, end=None) → ks.Series¶ Return highest indexes in each strings where the substring is fully contained between [start:end].
This is the same as
str.rfind()
except instead of returning -1, it raises a ValueError when the substring is not found. Equivalent to standardstr.rindex()
.- Parameters
- substr
Substring being searched.
- startint
Left edge index.

Examples
>>> s = ks.Series(['apple', 'oranges', 'bananas'])
>>> s.str.rindex('a') 0 0 1 2 2 5 dtype: int64
The following expression throws an exception:
>>> s.str.rindex('a', start=2)
