pandas.Index.symmetric_difference#
- Index.symmetric_difference(other, result_name=None, sort=None)[source]#
Compute the symmetric difference of two Index objects.
- Parameters
- otherIndex or array-like
- result_namestr
- sortFalse or None, default None
Whether to sort the resulting index. By default, the values are attempted to be sorted, but any TypeError from incomparable elements is caught by pandas.
None : Attempt to sort the result, but catch any TypeErrors from comparing incomparable elements.
False : Do not sort the result.
- Returns
- symmetric_differenceIndex
Notes
symmetric_difference
contains elements that appear in eitheridx1
oridx2
but not both. Equivalent to the Index created byidx1.difference(idx2) | idx2.difference(idx1)
with duplicates dropped.Examples
>>> idx1 = pd.Index([1, 2, 3, 4]) >>> idx2 = pd.Index([2, 3, 4, 5]) >>> idx1.symmetric_difference(idx2) Int64Index([1, 5], dtype='int64')
