Arrays and Scalars

Factory Function

This function is the main entry point to create an Arrow array from Python.

array(obj[, type, mask, size])

Create pyarrow.Array instance from a Python object

Array Types

An array’s Python class depends on its data type. Concrete array classes may expose data type-specific methods or properties.

Array()	The base class for all Arrow arrays.
BooleanArray	Concrete class for Arrow arrays of boolean data type.
FloatingPointArray	A base class for Arrow floating-point arrays.
IntegerArray	A base class for Arrow integer arrays.
Int8Array	Concrete class for Arrow arrays of int8 data type.
Int16Array	Concrete class for Arrow arrays of int16 data type.
Int32Array	Concrete class for Arrow arrays of int32 data type.
Int64Array	Concrete class for Arrow arrays of int64 data type.
NullArray	Concrete class for Arrow arrays of null data type.
NumericArray	A base class for Arrow numeric arrays.
UInt8Array	Concrete class for Arrow arrays of uint8 data type.
UInt16Array	Concrete class for Arrow arrays of uint16 data type.
UInt32Array	Concrete class for Arrow arrays of uint32 data type.
UInt64Array	Concrete class for Arrow arrays of uint64 data type.
BinaryArray	Concrete class for Arrow arrays of variable-sized binary data type.
StringArray	Concrete class for Arrow arrays of string (or utf8) data type.
FixedSizeBinaryArray	Concrete class for Arrow arrays of a fixed-size binary data type.
Time32Array	Concrete class for Arrow arrays of time32 data type.
Time64Array	Concrete class for Arrow arrays of time64 data type.
Date32Array	Concrete class for Arrow arrays of date32 data type.
Date64Array	Concrete class for Arrow arrays of date64 data type.
TimestampArray	Concrete class for Arrow arrays of timestamp data type.
Decimal128Array	Concrete class for Arrow arrays of decimal128 data type.
DictionaryArray	Concrete class for dictionary-encoded Arrow arrays.
ListArray	Concrete class for Arrow arrays of a list data type.
StructArray	Concrete class for Arrow arrays of a struct data type.
UnionArray	Concrete class for Arrow arrays of a Union data type.

Array Scalars

Indexing an array wraps the represented value in a scalar object whose concrete type depends on the array data type. You shouldn’t instantiate any of those classes directly.

NA	Singleton for null array elements.
Scalar	The base class for all array elements.
ArrayValue()	The base class for non-null array elements.
BooleanValue	Concrete class for boolean array elements.
Int8Value	Concrete class for int8 array elements.
Int16Value	Concrete class for int16 array elements.
Int32Value	Concrete class for int32 array elements.
Int64Value	Concrete class for int64 array elements.
UInt8Value	Concrete class for uint8 array elements.
UInt16Value	Concrete class for uint16 array elements.
UInt32Value	Concrete class for uint32 array elements.
UInt64Value	Concrete class for uint64 array elements.
FloatValue	Concrete class for float32 array elements.
DoubleValue	Concrete class for float64 array elements.
BinaryValue	Concrete class for variable-sized binary array elements.
StringValue	Concrete class for string (utf8) array elements.
FixedSizeBinaryValue	Concrete class for fixed-size binary array elements.
Time32Value	Concrete class for time32 array elements.
Time64Value	Concrete class for time64 array elements.
Date32Value	Concrete class for date32 array elements.
Date64Value	Concrete class for date64 array elements.
TimestampValue	Concrete class for timestamp array elements.
DecimalValue	Concrete class for decimal128 array elements.
DictionaryValue	Concrete class for dictionary-encoded array elements.
ListValue	Concrete class for list array elements.
