pandas.arrays.IntegerArray#

class pandas.arrays.IntegerArray(values, mask, copy=False)[source]#

Array of integer (optional missing) values.

Uses pandas.NA as the missing value.

Warning

IntegerArray is currently experimental, and its API or internal implementation may change without warning.

We represent an IntegerArray with 2 numpy arrays:

  • data: contains a numpy integer array of the appropriate dtype

  • mask: a boolean array holding a mask on the data, True is missing

To construct an IntegerArray from generic array-like input, use pandas.array() with one of the integer dtypes (see examples).

See Nullable integer data type for more.

Parameters:
valuesnumpy.ndarray

A 1-d integer-dtype array.

masknumpy.ndarray

A 1-d boolean-dtype array indicating missing values.

copybool, default False

Whether to copy the values and mask.

Methods

None
Returns:
IntegerArray

Examples

Create an IntegerArray with pandas.array().

>>> int_array = pd.array([1, None, 3], dtype=pd.Int32Dtype())
>>> int_array
<IntegerArray>
[1, <NA>, 3]
Length: 3, dtype: Int32

String aliases for the dtypes are also available. They are capitalized.

>>> pd.array([1, None, 3], dtype="Int32")
<IntegerArray>
[1, <NA>, 3]
Length: 3, dtype: Int32

>>> pd.array([1, None, 3], dtype="UInt16")
<IntegerArray>
[1, <NA>, 3]
Length: 3, dtype: UInt16
