pandas.Series.str.rindex

Series.str.rindex(sub, start=0, end=None)

Return highest indexes in each string in Series/Index.

Each of the returned indexes corresponds to the position 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 standard str.rindex.

Parameters

substr

Substring being searched.

startint

Left edge index.

endint

Right edge index.

Returns

Series or Index of object
