pyspark.pandas.Series.str.rindex

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

Return highest indexes in each string 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 of int

Series of highest matching indexes.

Examples

>>> s = ps.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)
