Python Pandas - Check if an interval is empty if closed from the left side


To check if an interval is empty if closed from the left side, use the interval.is_empty property. At first, import the required libraries −

import pandas as pd

Interval closed from the left. Interval set using the "closed" parameter with value "left"

interval = pd.Interval(0, 0, closed='left')

Display the interval

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

Check whether interval is empty

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

Example

Following is the code

import pandas as pd

# interval closed from the left
# Interval set using the "closed" parameter with value "left"
interval = pd.Interval(0, 0, closed='left')

# display the interval
print("Interval...\n",interval)

# display the interval length
print("\nInterval length...\n",interval.length)

# check whether interval 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
