pyarrow.binary#

pyarrow.binary(intlength=-1)#

Create variable-length or fixed size binary type.

Parameters:

lengthint, optional, default -1

If length == -1 then return a variable length binary type. If length isgreater than or equal to 0 then return a fixed size binary type ofwidthlength.

Examples

Create an instance of a variable-length binary type:

>>>importpyarrowaspa>>>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]
