pandas.DataFrame.slice_shift — pandas 0.16.2 documentation (original) (raw)
DataFrame.slice_shift(periods=1, axis=0)¶
Equivalent to shift without copying data. The shifted data will not include the dropped periods and the shifted axis will be smaller than the original.
| Parameters: | periods : int Number of periods to move, can be positive or negative |
|---|---|
| Returns: | shifted : same type as caller |
Notes
While the slice_shift is faster than shift, you may pay for it later during alignment.
