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
