pandas.IntervalIndex.get_loc

IntervalIndex.get_loc(key, method=None) [source]

Get integer location, slice or boolean mask for requested label.

Parameters:
key : label

method : {None}, optional

  • default: matches where the label is within an interval only.
Returns:
loc : int if unique index, slice if monotonic index, else mask

Examples

>>> i1, i2 = pd.Interval(0, 1), pd.Interval(1, 2)
>>> index = pd.IntervalIndex([i1, i2])
>>> index.get_loc(1)
0

You can also supply an interval or an location for a point inside an interval.

>>> index.get_loc(pd.Interval(0, 2))
array([0, 1], dtype=int64)
>>> index.get_loc(1.5)
1

If a label is in several intervals, you get the locations of all the relevant intervals.

>>> i3 = pd.Interval(0, 2)
>>> overlapping_index = pd.IntervalIndex([i2, i3])
>>> overlapping_index.get_loc(1.5)
array([0, 1], dtype=int64)
