pyspark.pandas.Series.str.index¶
-
str.index(sub: str, start: int = 0, end: Optional[int] = None) → pyspark.pandas.series.Series¶ Return lowest indexes in each string where the substring is fully contained between [start:end].
This is the same as
str.find()except instead of returning -1, it raises a ValueError when the substring is not found. Equivalent to standardstr.index().- Parameters
- substr
Substring being searched.
- startint
Left edge index.
- endint
Right edge index.
- Returns
- Series of int
Series of lowest matching indexes.
Examples
>>> s = ps.Series(['apple', 'oranges', 'bananas'])
>>> s.str.index('a') 0 0 1 2 2 1 dtype: int64
The following expression throws an exception:
>>> s.str.index('a', start=2)
