Check If an Open Interval Set is Empty in Python Pandas

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

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
