pandas.Flags#

classpandas.Flags(obj,*,allows_duplicate_labels)[source]#

Flags that apply to pandas objects.

Parameters:

objSeries or DataFrame

The object these flags are associated with.

allows_duplicate_labelsbool, default True

Whether to allow duplicate labels in this object. By default,duplicate labels are permitted. Setting this toFalse willcause anerrors.DuplicateLabelError to be raised whenindex (or columns for DataFrame) is not unique, or anysubsequent operation on introduces duplicates.SeeDisallowing Duplicate Labels for more.

Warning

This is an experimental feature. Currently, many methods fail topropagate theallows_duplicate_labels value. In future versionsit is expected that every method taking or returning one or moreDataFrame or Series objects will propagateallows_duplicate_labels.

Examples

Attributes can be set in two ways:

>>>df=pd.DataFrame()>>>df.flags<Flags(allows_duplicate_labels=True)>>>>df.flags.allows_duplicate_labels=False>>>df.flags<Flags(allows_duplicate_labels=False)>

>>>df.flags['allows_duplicate_labels']=True>>>df.flags<Flags(allows_duplicate_labels=True)>

Attributes

allows_duplicate_labels

Whether this object allows duplicate labels.
