Python Pandas IntervalIndex - Indicates if an interval is empty (contains no points)

To indicate if an interval is empty (contains no points), use the interval.is_empty property in Pandas. At first, import the required libraries −

import pandas as pd

Create IntervalIndex −

interval = pd.IntervalIndex.from_arrays([0, 0], [0, 0]) 

Display the interval −

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

Check if the interval is empty −

print("\nIs the interval empty?\n",interval.is_empty) 

Example

Following is the code −

import pandas as pd # Create IntervalIndex interval = pd.IntervalIndex.from_arrays([0, 0], [0, 0]) # Display the interval print("IntervalIndex...\n",interval) # Display the interval length print("\nIntervalIndex length...\n",interval.length) # check if the interval is empty print("\nIs the interval empty?\n",interval.is_empty)

Output

This will produce the following output −

IntervalIndex... IntervalIndex([(0, 0], (0, 0]], dtype='interval[int64, right]') IntervalIndex length... Int64Index([0, 0], dtype='int64') Is the interval empty? [ True True]
