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=<no_default>, check_datetimelike_compat=False, check_categorical=True, check_category_order=True, check_freq=True, check_flags=True, rtol=<no_default>, atol=<no_default>, obj='Series', *, check_index=True, check_like=False)[source]
-
Check that left and right Series are equal.
- Parameters:
-
- left:Series
- right:Series
- check_dtype:bool, default True
-
Whether to check the Series dtype is identical.
- check_index_type:bool or {‘equiv’}, default ‘equiv’
-
Whether to check the Index class, dtype and inferred_type are identical.
- check_series_type:bool, default True
-
Whether to check the Series class is identical.
- check_names:bool, default True
-
Whether to check the Series and Index names attribute.
- check_exact:bool, 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
andatol
are specified. - check_datetimelike_compat:bool, default False
-
Compare datetime-like which is comparable ignoring dtype.
- check_categorical:bool, default True
-
Whether to compare internal Categorical exactly.
- check_category_order:bool, default True
-
Whether to compare category order of internal Categoricals.
- check_freq:bool, default True
-
Whether to check the freq attribute on a DatetimeIndex or TimedeltaIndex.
- check_flags:bool, default True
-
Whether to check the flags attribute.
- rtol:float, default 1e-5
-
Relative tolerance. Only used when check_exact is False.
- atol:float, default 1e-8
-
Absolute tolerance. Only used when check_exact is False.
- obj:str, default ‘Series’
-
Specify object name being compared, internally used to show appropriate assertion message.
- check_index:bool, default True
-
Whether to check index equivalence. If False, then compare only values.
Added in version 1.3.0.
- check_like:bool, 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.
Added in version 1.5.0.
