pandas.testing.assert_index_equal#
- pandas.testing.assert_index_equal(left, right, exact='equiv', check_names=True, check_exact=True, check_categorical=True, check_order=True, rtol=1e-05, atol=1e-08, obj='Index')[source]#
Check that left and right Index are equal.
- Parameters
- leftIndex
- rightIndex
- exactbool or {‘equiv’}, default ‘equiv’
Whether to check the Index class, dtype and inferred_type are identical. If ‘equiv’, then RangeIndex can be substituted for Index with an int64 dtype as well.
- check_namesbool, default True
Whether to check the names attribute.
- check_exactbool, default True
Whether to compare number exactly.
- check_categoricalbool, default True
Whether to compare internal Categorical exactly.
- check_orderbool, default True
Whether to compare the order of index entries as well as their values. If True, both indexes must contain the same elements, in the same order. If False, both indexes must contain the same elements, but in any order.
New in version 1.2.0.
- rtolfloat, default 1e-5
Relative tolerance. Only used when check_exact is False.
New in version 1.1.0.
- atolfloat, default 1e-8
Absolute tolerance. Only used when check_exact is False.
New in version 1.1.0.
- objstr, default ‘Index’
Specify object name being compared, internally used to show appropriate assertion message.
Examples
>>> from pandas import testing as tm >>> a = pd.Index([1, 2, 3]) >>> b = pd.Index([1, 2, 3]) >>> tm.assert_index_equal(a, b)
