Shift index by desired number of periods with an optional time freq.

When freq is not passed, shift the index without realigning the data. If freq is passed (in this case, the index must be date or datetime, or it will raise a NotImplementedError), the index will be increased using the periods and the freq.

param periods

Number of periods to shift. Can be positive or negative.

param freq
DateOffset, tseries.offsets, timedelta, or str, optional

Offset to use from the tseries module or time rule (e.g. ‘EOM’). If freq is specified then the index values are shifted but the data is not realigned. That is, use freq if you would like to extend the index when shifting and preserve the original data.

param axis
{0 or ‘index’, 1 or ‘columns’, None}, default None

Shift direction.

param fill_value
object, optional

The scalar value to use for newly introduced missing values. the default depends on the dtype of self. For numeric data, np.nan is used. For datetime, timedelta, or period data, etc. NaT is used. For extension dtypes, self.dtype.na_value is used.

Changed in version 0.24.0.


DataFrame Copy of input object, shifted.
