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

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

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)
