To check if an Interval is closed on the left side, use the interval.closed_left property. At first, import the required libraries −

import pandas as pd

Interval set using the "closed" parameter with value "left" i.e. [0, 5) is described by 0 <= x < 5 when closed='left'

interval = pd.Interval(left=0, right=20, closed='left')


Display the interval

print("Interval...",interval)

Check whether the interval is closed on the left-side

print("Checking whether the Interval is closed on the left...", interval.closed_left)


## Example

Following is the code

import pandas as pd

# Interval set using the "closed" parameter with value "left"
# i.e. [0, 5) is described by 0 <= x < 5 when closed='left'
interval = pd.Interval(left=0, right=20, closed='left')

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

# display the interval length
print("Interval length...",interval.length)

# check whether the interval is closed on the left-side
print("Checking whether the Interval is closed on the left...", interval.closed_left)

## Output

This will produce the following code

Interval...
[0, 20)

Interval length...
20

Checking whether the Interval is closed on the left...
True
