DataFrame.slice_shift()

DataFrame.slice_shift(periods=1, axis=0) [source]

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:

Parameters:	periods : int Number of periods to move, can be positive or negative
Returns:	shifted : same type as caller

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.
