# Python Pandas IntervalIndex - Check if Intervals that share closed endpoints overlap

To check if Intervals that share closed endpoints overlap, use the **IntervalIndex.is_overlapping** property. At first, import the required libraries −

import pandas as pd

Create IntervalIndex. The intervals are closed on both the sides since the "closed" parameter is set "both" −

interval = pd.interval_range(0, 8, closed='both')

Display the interval −

print("IntervalIndex...\n",interval)

Check if the Intervals that share closed endpoints overlap −

print("\nDoes the Intervals that share closed endpoints overlap?\n",interval.is_overlapping)

## Example

Following is the code −

import pandas as pd # Create IntervalIndex # The intervals are closed on both the sides since the "closed" parameter is set "both" interval = pd.interval_range(0, 8, closed='both') # Display the interval print("IntervalIndex...\n",interval) # Display the interval length print("\nIntervalIndex length...\n",interval.length) # Check if the Intervals that share closed endpoints overlap print("\nDoes the Intervals that share closed endpoints overlap?\n",interval.is_overlapping)

## Output

This will produce the following output −

IntervalIndex... IntervalIndex([[0, 1], [1, 2], [2, 3], [3, 4], [4, 5], [5, 6], [6, 7], [7, 8]], dtype='interval[int64, both]') IntervalIndex length... Int64Index([1, 1, 1, 1, 1, 1, 1, 1], dtype='int64') Does the Intervals that share closed endpoints overlap? True
