Python Pandas IntervalIndex - Check if an interval that contains points is empty or not

To check if an interval that contains points is empty or not, use the IntervalIndex.is_empty property in Pandas.

At first, import the required libraries −

import pandas as pd

Create IntervalIndex −

interval = pd.IntervalIndex.from_arrays([0, 1], [1, 2], closed='right')

Display the interval −

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

Check if the interval that contains points is empty or not −

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, 1], [1, 2], closed='right')

# Display the interval
print("IntervalIndex...\n",interval)

# Display the interval length
print("\nIntervalIndex length...\n",interval.length)

# check if the interval that contains points is empty or not
print("\nIs the interval empty?\n",interval.is_empty)

Output

This will produce the following output −

IntervalIndex...
IntervalIndex([(0, 1], (1, 2]], dtype='interval[int64, right]')

IntervalIndex length...
Int64Index([1, 1], dtype='int64')

Is the interval empty?
[False False]
