Python Pandas - Check whether the intervals in IntervalArray are closed on the left-side, right-side, both or neither

To check whether the intervals in IntervalArray are closed on the left-side, right-side, both or neither, use the array.closed property.

At first, import the required libraries −

import pandas as pd

Create two Interval objects. Closed intervals set using the "closed" parameter with value "both". A closed interval (in mathematics denoted by square brackets) contains its endpoints, i.e. the closed interval [0, 5] is characterized by the conditions 0 <= x <= 5 −

interval1 = pd.Interval(10, 25, closed='both') interval2 = pd.Interval(15, 70, closed='both')

Display the intervals −

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

Construct a new IntervalArray from Interval objects −

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

Check whether the intervals in the Interval Array is closed on the left-side, right-side, both or neither −

print("\nChecking whether the intervals is closed...\n",array.closed)

Example

Following is the code −

import pandas as pd # Create two Interval objects # Closed intervals set using the "closed" parameter with value "both" # A closed interval (in mathematics denoted by square brackets) contains its endpoints, # i.e. the closed interval [0, 5] is characterized by the conditions 0 <= x <= 5 interval1 = pd.Interval(10, 25, closed='both') interval2 = pd.Interval(15, 70, closed='both') # 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) # check whether the intervals in the Interval Array is closed on the left-side, right-side, # both or neither print("\nChecking whether the intervals is closed...\n",array.closed)

Output

This will produce the following code −

Interval1... [10, 25] Interval2... [15, 70] Our IntervalArray... <IntervalArray> [[10, 25], [15, 70]] Length: 2, dtype: interval[int64, both] Our IntervalArray length... Int64Index([15, 55], dtype='int64') Checking whether the intervals is closed... Both
