pandas.testing.assert_extension_array_equal(left, right, check_dtype=True, index_values=None, check_exact=False, rtol=1e-05, atol=1e-08, obj='ExtensionArray')[source]#

Check that left and right ExtensionArrays are equal.

Parameters:

left, rightExtensionArray: The two arrays to compare.
check_dtypebool, default True: Whether to check if the ExtensionArray dtypes are identical.
index_valuesnumpy.ndarray, default None: Optional index (shared by both left and right), used in output.
check_exactbool, default False: Whether to compare number exactly.
rtolfloat, default 1e-5: Relative tolerance. Only used when check_exact is False.
atolfloat, default 1e-8: Absolute tolerance. Only used when check_exact is False.
objstr, default ‘ExtensionArray’: Specify object name being compared, internally used to show appropriate assertion message.

New in version 2.0.0.

Notes

Missing values are checked separately from valid values. A mask of missing values is computed for each and checked to match. The remaining all-valid values are cast to object dtype and checked.

Examples

>>> from pandas import testing as tm
>>> a = pd.Series([1, 2, 3, 4])
>>> b, c = a.array, a.array
>>> tm.assert_extension_array_equal(b, c)
