pandas.Index.slice_indexer

Index.slice_indexer(start=None, end=None, step=None, kind=None)

For an ordered or unique index, compute the slice indexer for input labels and step.

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

kind : string, default None

Returns:

indexer : 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)

>>> idx = pd.MultiIndex.from_arrays([list('abcd'), list('efgh')])
>>> idx.slice_indexer(start='b', end=('c', 'g'))
slice(1, 3)
