pandas.CategoricalIndex.equals#
- CategoricalIndex.equals(other)[source]#
Determine if two CategoricalIndex objects contain the same elements.
- Returns:
- bool
True
if twopandas.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
