bigframes.pandas.api.typing.StringMethods.find

StringMethods.find(sub: str, start: int | None = None, end: int | None = None) → T

Return lowest indexes in each strings in the Series/Index.

Each of returned indexes corresponds to the position where the substring is fully contained between [start:end]. Return -1 on failure. Equivalent to standard str.find().

Examples:

>>> import bigframes.pandas as bpd

>>> ser = bpd.Series(["cow_", "duck_", "do_ve"])
>>> ser.str.find("_")
0    3
1    4
2    2
dtype: Int64

Parameters:

• sub (str) – Substring being searched.

• start (int, default 0) – Left edge index.

• end (int, default None) – Right edge index.

Returns:

Series with lowest indexes in each strings.

Return type:

bigframes.series.Series
