pandas.CategoricalIndex.equals#

CategoricalIndex.equals(other)[source]#

Determine if two CategoricalIndex objects contain the same elements.

Returns:

bool: True if two pandas.CategoricalIndex objects have equal elements, False otherwise.

Examples

>>> ci = pd.CategoricalIndex(['a', 'b', 'c', 'a', 'b', 'c'])
>>> ci2 = pd.CategoricalIndex(pd.Categorical(['a', 'b', 'c', 'a', 'b', 'c']))
>>> ci.equals(ci2)
True

The order of elements matters.

>>> ci3 = pd.CategoricalIndex(['c', 'b', 'a', 'a', 'b', 'c'])
>>> ci.equals(ci3)
False

The orderedness also matters.

>>> ci4 = ci.as_ordered()
>>> ci.equals(ci4)
False

The categories matter, but the order of the categories matters only when ordered=True.

>>> ci5 = ci.set_categories(['a', 'b', 'c', 'd'])
>>> ci.equals(ci5)
False

>>> ci6 = ci.set_categories(['b', 'c', 'a'])
>>> ci.equals(ci6)
True
>>> ci_ordered = pd.CategoricalIndex(['a', 'b', 'c', 'a', 'b', 'c'],
...                                  ordered=True)
>>> ci2_ordered = ci_ordered.set_categories(['b', 'c', 'a'])
>>> ci_ordered.equals(ci2_ordered)
False
