pyarrow.binary¶
- pyarrow.binary(int length=-1)¶
Create variable-length or fixed size binary type.
- Parameters:
- length
int
, optional, default -1 If length == -1 then return a variable length binary type. If length is greater than or equal to 0 then return a fixed size binary type of width length.
- length
Examples
Create an instance of a variable-length binary type:
>>> import pyarrow as pa >>> pa.binary() DataType(binary)
and use the variable-length binary type to create an array:
>>> pa.array(['foo', 'bar', 'baz'], type=pa.binary()) <pyarrow.lib.BinaryArray object at ...> [ 666F6F, 626172, 62617A ]
Create an instance of a fixed-size binary type:
>>> pa.binary(3) FixedSizeBinaryType(fixed_size_binary[3])
and use the fixed-length binary type to create an array: >>> pa.array([‘foo’, ‘bar’, ‘baz’], type=pa.binary(3)) <pyarrow.lib.FixedSizeBinaryArray object at …> [
666F6F, 626172, 62617A
