# pandas.IntervalIndex.get_loc

IntervalIndex.get_loc(key)

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

  The get_loc method is used to retrieve the integer index, a slice for slicing objects, or a boolean mask indicating the presence of the label in the IntervalIndex.

  Parameters:
    key label

      The value or range to find in the IntervalIndex.

  Returns:
    int if unique index, slice if monotonic index, else mask

      The position or positions found. This could be a single number, a range, or an array of true/false values indicating the position(s) of the label.

  See also

  `IntervalIndex.get_indexer_non_unique`

    Compute indexer and mask for new index given the current index.

  `Index.get_loc`

    Similar method in the base Index class.

  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 a point inside an interval.

      >>> 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([i1, i2, i3])
      >>> overlapping_index.get_loc(0.5)
      array([ True, False,  True])

  Only exact matches will be returned if an interval is provided.

      >>> index.get_loc(pd.Interval(0, 1))
      0
