# pandas.arrays.IntervalArray.left

property IntervalArray.left

  Return the left endpoints of each Interval in the IntervalArray as an Index.

  This property provides access to the left endpoints of the intervals contained within the IntervalArray. This can be useful for analyses where the starting point of each interval is of interest, such as in histogram creation, data aggregation, or any scenario requiring the identification of the beginning of defined ranges. This property returns a `pandas.Index` object containing the midpoint for each interval.

  `arrays.IntervalArray.right`

    Return the right endpoints of each Interval in the IntervalArray as an Index.

  `arrays.IntervalArray.mid`

    Return the midpoint of each Interval in the IntervalArray as an Index.

  `arrays.IntervalArray.contains`

    Check elementwise if the Intervals contain the value.

  Examples

      >>> interv_arr = pd.arrays.IntervalArray([pd.Interval(0, 1), pd.Interval(2, 5)])
      >>> interv_arr
      <IntervalArray>
      [(0, 1], (2, 5]]
      Length: 2, dtype: interval[int64, right]
      >>> interv_arr.left
      Index([0, 2], dtype='int64')
