Python Pandas - Check if an interval set as open is empty



To check if an interval set as open is empty, use the interval.is_empty property. At first, import the required libraries −

import pandas as pd

Open interval set using the "closed" parameter with value "neither". An open interval (in mathematics denoted by square brackets) does not contains its endpoints, # i.e. the open interval [0, 5] is characterized by the conditions 0 < x < 5

interval = pd.Interval(0, 0, closed='neither')

Display the interval

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

Check whether interval is empty when it is open i.e. no endpoints. An Interval that does not contain any points is empty

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

Example

Following is the code

Open Compiler
import pandas as pd # Open interval set using the "closed" parameter with value "neither" # An open interval (in mathematics denoted by square brackets) does not contains its endpoints, # i.e. the open interval [0, 5] is characterized by the conditions 0 < x < 5. interval = pd.Interval(0, 0, closed='neither') # display the interval print("Interval...\n",interval) # display the interval length print("\nInterval length...\n",interval.length) # check whether interval is empty when it is open i.e. no endpoints # An Interval that does not contain any points is empty: print("\nIs Interval empty? \n",interval.is_empty)

Output

This will produce the following code

Interval...
(0, 0)

Interval length...
0

Is Interval empty?
True
