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...
",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("
Is Interval empty?
",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...
",interval)
# display the interval length
print("
Interval length...
",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("
Is Interval empty?
",interval.is_empty)Output
This will produce the following code
Interval... (0, 0) Interval length... 0 Is Interval empty? True
