pandas.testing.assert_series_equal

pandas.testing.assert_series_equal(left, right, check_dtype=True, check_index_type='equiv', check_series_type=True, check_names=True, check_exact=_NoDefault.no_default, check_datetimelike_compat=False, check_categorical=True, check_category_order=True, check_freq=True, check_flags=True, rtol=_NoDefault.no_default, atol=_NoDefault.no_default, obj='Series', *, check_index=True, check_like=False)

Check that left and right Series are equal.

Parameters:

leftSeries

rightSeries

check_dtypebool, default True

Whether to check the Series dtype is identical.

check_index_typebool or {‘equiv’}, default ‘equiv’

Whether to check the Index class, dtype and inferred_type are identical.

check_series_typebool, default True

Whether to check the Series class is identical.

check_namesbool, default True

Whether to check the Series and Index names attribute.

check_exactbool, default False

Whether to compare number exactly.

Changed in version 2.2.0: Defaults to True for integer dtypes if none of check_exact, rtol and atol are specified.

check_datetimelike_compatbool, default False

Compare datetime-like which is comparable ignoring dtype.

check_categoricalbool, default True

Whether to compare internal Categorical exactly.

check_category_orderbool, default True

Whether to compare category order of internal Categoricals.

check_freqbool, default True

Whether to check the freq attribute on a DatetimeIndex or TimedeltaIndex.

check_flagsbool, default True

Whether to check the flags attribute.

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 ‘Series’

Specify object name being compared, internally used to show appropriate assertion message.

check_indexbool, default True

Whether to check index equivalence. If False, then compare only values.

New in version 1.3.0.

check_likebool, default False

If True, ignore the order of the index. Must be False if check_index is False. Note: same labels must be with the same data.

New in version 1.5.0.

Examples

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