pandas.arrays.PandasArray¶

class pandas.arrays.PandasArray(values, copy=False)[source]¶

A pandas ExtensionArray for NumPy data.

New in version 0.24.0.

This is mostly for internal compatibility, and is not especially useful on its own.

Parameters:	values : ndarray The NumPy ndarray to wrap. Must be 1-dimensional. copy : bool, default False Whether to copy values.

Notes

Operations like + and applying ufuncs requires NumPy>=1.13.

Attributes

`dtype`	An instance of ‘ExtensionDtype’.
`nbytes`	The number of bytes needed to store this object in memory.
`ndim`	Extension Arrays are only allowed to be 1-dimensional.
`shape`	Return a tuple of the array dimensions.

Methods

`argsort`([ascending, kind])	Return the indices that would sort this array.
`astype`(dtype[, copy])	Cast to a NumPy array with ‘dtype’.
`copy`([deep])	Return a copy of the array.
`dropna`()	Return ExtensionArray without NA values
`factorize`([na_sentinel])	Encode the extension array as an enumerated type.
`fillna`([value, method, limit])	Fill NA/NaN values using the specified method.
`isna`()	A 1-D array indicating if each value is missing.
`repeat`(repeats[, axis])	Repeat elements of a ExtensionArray.
`searchsorted`(value[, side, sorter])	Find indices where elements should be inserted to maintain order.
`shift`([periods, fill_value])	Shift values by desired number.
`take`(indices[, allow_fill, fill_value])	Take elements from an array.
`to_numpy`([dtype, copy])	Convert the PandasArray to a `numpy.ndarray`.
`unique`()	Compute the ExtensionArray of unique values.
