modin.pandas.Index.slice_indexer¶

Index.slice_indexer(start: Hashable | None = None, end: Hashable | None = None, step: int | None = None) → slice[source]¶

Compute the slice indexer for input labels and step.

Index needs to be ordered and unique.

Parameters:

• start (label, default None) – If None, defaults to the beginning.

• end (label, default None) – If None, defaults to the end.

• step (int, default None) –

Returns:

The slice of indices

Return type:

slice

Raises:

KeyError – If key does not exist, or key is not unique and index is not ordered.

Notes

This function assumes that the data is sorted, so use at your own peril

Examples

This is a method on all index types. For example you can do:

>>> idx = pd.Index(list('abcd'))
>>> idx.slice_indexer(start='b', end='c')
slice(1, 3, None)
