By default, duplicate labels are permitted. Setting this to ``False`` will cause an :class:`errors.DuplicateLabelError` to be raised when `index` (or columns for DataFrame) is not unique, or any subsequent operation on introduces duplicates. See :ref:`duplicates.disallow` for more. .. warning:: This is an experimental feature. Currently, many methods fail to propagate the ``allows_duplicate_labels`` value. In future versions it is expected that every method taking or returning one or more DataFrame or Series objects will propagate ``allows_duplicate_labels``. Notes ----- Attributes can be set in two ways >>> df = pd.DataFrame() >>> df.flags >>> df.flags.allows_duplicate_labels = False >>> df.flags >>> df.flags['allows_duplicate_labels'] = True >>> df.flags allows_duplicate_labelscCs||_t||_dSN)_allows_duplicate_labelsweakrefref_obj)selfobjrr Q/home/ja/django-apps/lartica_env/lib/python3.9/site-packages/pandas/core/flags.py__init__/szFlags.__init__)returncCs|jS)a Whether this object allows duplicate labels. Setting ``allows_duplicate_labels=False`` ensures that the index (and columns of a DataFrame) are unique.
