bigframes.geopandas.GeoSeries.duplicated#

GeoSeries.duplicated(keep:str='first')→Series#

Indicate duplicate Series values.

Duplicated values are indicated asTrue values in the resultingSeries. Either all duplicates, all except the first or all except thelast occurrence of duplicates can be indicated.

Examples:

>>>importbigframes.pandasasbpd

By default, for each set of duplicated values, the first occurrence isset on False and all others on True:

>>>animals=bpd.Series(['llama','cow','llama','beetle','llama'])>>>animals.duplicated()0    False1    False2     True3    False4     Truedtype: boolean

which is equivalent to

>>>animals.duplicated(keep='first')0    False1    False2     True3    False4     Truedtype: boolean

By using ‘last’, the last occurrence of each set of duplicated valuesis set on False and all others on True:

>>>animals.duplicated(keep='last')0     True1    False2     True3    False4    Falsedtype: boolean

By setting keep on False, all duplicates are True:

>>>animals.duplicated(keep=False)0     True1    False2     True3    False4     Truedtype: boolean
Parameters:

keep ({'first','last',False},default 'first') –

Method to handle dropping duplicates:

’first’ : Mark duplicates asTrue except for the firstoccurrence.‘last’ : Mark duplicates asTrue except for the lastoccurrence.False : Mark all duplicates asTrue.

Returns:

Series indicating whether each value has occurred in thepreceding values.

Return type:

bigframes.pandas.Series
