find

pylibcudf.strings.find.contains(signatures, args, kwargs, defaults, _fused_sigindex_ref=[None])

Returns a column of boolean values for each string where true indicates the corresponding target string was found within that string in the provided column.

target may be a Column or a Scalar.

If target is a scalar, the scalar will be searched for in each string. If target is a column, the corresponding string in the column will be searched for in each string.

For details, see contains().

Parameters:

inputColumn

The input strings

targetUnion[Column, Scalar]

String to search for in each string

Returns:

pylibcudf.Column

New boolean column with True for each string that contains the target

pylibcudf.strings.find.ends_with(signatures, args, kwargs, defaults, _fused_sigindex_ref=[None])

Returns a column of boolean values for each string where true indicates the target string was found at the end of the string in the provided column.

target may be a Column or a Scalar.

If target is a scalar, the scalar will be searched for in each string. If target is a column, the corresponding string in the column will be searched for in each string.

For details, see ends_with().

Parameters:

inputColumn

The input strings

targetUnion[Column, Scalar]

String to search for at the end of each string

Returns:

pylibcudf.Column

New boolean column with True for each string that ends with the target

pylibcudf.strings.find.find(signatures, args, kwargs, defaults, _fused_sigindex_ref=[None])

Returns a column of character position values where the target string is first found in each string of the provided column.

target may be a Column or a Scalar.

If target is a scalar, the scalar will be searched for in each string. If target is a column, the corresponding string in the column will be searched for in each string.

For details, see find().

Parameters:

inputColumn

The input strings

targetUnion[Column, Scalar]

String to search for in each string

startsize_type

First character position to include in the search

stopsize_type

Last position (exclusive) to include in the search. Default of -1 will search to the end of the string.

Returns:

pylibcudf.Column

New integer column with character position values

pylibcudf.strings.find.rfind(Column input, Scalar target, size_type start=0, size_type stop=-1) → Column

Returns a column of character position values where the target string is first found searching from the end of each string.

For details, see rfind().

Parameters:

inputColumn

The input strings

targetScalar

String to search for in each string

startsize_type

First character position to include in the search

stopsize_type

Last position (exclusive) to include in the search. Default of -1 will search to the end of the string.

Returns:

pylibcudf.Column

New integer column with character position values

pylibcudf.strings.find.starts_with(signatures, args, kwargs, defaults, _fused_sigindex_ref=[None])

Returns a column of boolean values for each string where true indicates the target string was found at the beginning of the string in the provided column.

target may be a Column or a Scalar.

If target is a scalar, the scalar will be searched for in each string. If target is a column, the corresponding string in the column will be searched for in each string.

For details, see starts_with().

Parameters:

inputColumn

The input strings

targetUnion[Column, Scalar]

String to search for at the beginning of each string

Returns:

pylibcudf.Column

New boolean column with True for each string that starts with the target
