# pandas.Series.backfill

Series.backfill(*, axis=None, inplace=False, limit=None, downcast=<no_default>)

  Fill NA/NaN values by using the next valid observation to fill the gap.

  Deprecated since version 2.0: Series/DataFrame.backfill is deprecated. Use Series/DataFrame.bfill instead.

  Returns:
    Series/DataFrame or None

      Object with missing values filled or None if `inplace=True`.
