pandas.Series.reindex

Series.reindex(index=None, method=None, level=None, copy=True)

Conform Series to new index with optional filling logic, placing NA/NaN in locations having no value in the previous index. A new object is produced unless the new index is equivalent to the current one and copy=False

Parameters :

index : array-like or Index

New labels / index to conform to. Preferably an Index object to avoid duplicating data

method : {‘backfill’, ‘bfill’, ‘pad’, ‘ffill’, None}

Method to use for filling holes in reindexed Series pad / ffill: propagate LAST valid observation forward to next valid backfill / bfill: use NEXT valid observation to fill gap

copy : boolean, default True

Return a new object, even if the passed indexes are the same

level : int or name

Broadcast across a level, matching Index values on the passed MultiIndex level

Returns :

reindexed : Series
