dask.dataframe.Index.between
dask.dataframe.Index.between¶
- Index.between(left, right, inclusive='both')¶
Return boolean Series equivalent to left <= series <= right.
This docstring was copied from pandas.core.series.Series.between.
Some inconsistencies with the Dask version may exist.
This function returns a boolean vector containing True wherever the corresponding Series element is between the boundary values left and right. NA values are treated as False.
- Parameters
- leftscalar or list-like
Left boundary.
- rightscalar or list-like
Right boundary.
- inclusive{“both”, “neither”, “left”, “right”}
Include boundaries. Whether to set each bound as closed or open.
Changed in version 1.3.0.
- Returns
- Series
Series representing whether each element is between left and right (inclusive).
Notes
This function is equivalent to
(left <= ser) & (ser <= right)
Examples
>>> s = pd.Series([2, 0, 4, 8, np.nan])
Boundary values are included by default:
>>> s.between(1, 4) 0 True 1 False 2 True 3 False 4 False dtype: bool
With inclusive set to
"neither"
boundary values are excluded:>>> s.between(1, 4, inclusive="neither") 0 True 1 False 2 False 3 False 4 False dtype: bool
left and right can be any scalar value:
>>> s = pd.Series(['Alice', 'Bob', 'Carol', 'Eve']) >>> s.between('Anna', 'Daniel') 0 False 1 True 2 True 3 False dtype: bool
