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_labelsNone)returncCs||_t||_dSN)_allows_duplicate_labelsweakrefref_obj)selfobjrrJ/home/sam/Atlas/atlas_env/lib/python3.8/site-packages/pandas/core/flags.py__init__1szFlags.__init__boolcCs|jS)a Whether this object allows duplicate labels.
