Python - Create a Pandas array for interval data

To create a Pandas array for interval data, use the pandas.arrays.IntervalArray() method. At first, import the required libraries −

import pandas as pd

Create two Interval objects −

interval1 = pd.Interval(10, 30) interval2 = pd.Interval(30, 70)

Display the intervals −

print("Interval1...\n",interval1) print("Interval2...\n",interval2)

Construct a new IntervalArray from Interval objects −

array = pd.arrays.IntervalArray([interval1,interval2]) 

Example

Following is the code −

import pandas as pd # Create two Interval objects interval1 = pd.Interval(10, 30) interval2 = pd.Interval(30, 70) # display the intervals print("Interval1...\n",interval1) print("Interval2...\n",interval2) # Construct a new IntervalArray from Interval objects array = pd.arrays.IntervalArray([interval1,interval2]) # Display the IntervalArray print("\nOur IntervalArray...\n",array) # Getting the length of IntervalArray # Returns an Index with entries denoting the length of each Interval in the IntervalArray print("\nOur IntervalArray length...\n",array.length)

Output

This will produce the following code −

Interval1... (10, 30] Interval2... (30, 70] Our IntervalArray... <IntervalArray> [(10, 30], (30, 70]] Length: 2, dtype: interval[int64, right] Our IntervalArray length... Int64Index([20, 40], dtype='int64')
