Python Pandas - Create a half-closed time interval and check for existence of endpoints

PythonServer Side ProgrammingProgramming

To create a half-closed time interval, use the pandas.Interval() and set the closed parameter to right. To check for existence of endpoints, use the in property.

At first, import the required libraries −

import pandas as pd

Half-Closed interval set using the "closed" parameter with value "right". Half-Closed i.e. (0, 5] is described by 0 < x <= 5 (closed='right')

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

Display the interval

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

Check for the existence of an element in an Interval. This shows that closed = right contain only the right-most endpoint

print("\nThe left-most element exists in the Interval? = \n",0 in interval)
print("\nThe right-most element exists in the Interval? = \n",20 in interval)

Example

Following is the code

import pandas as pd

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

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

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

# check for the existence of an element in an Interval
# This shows that closed = right contain only the right-most endpoint
print("\nThe left-most element exists in the Interval? = \n",0 in interval)
print("\nThe right-most element exists in the Interval? = \n",20 in interval)

Output

This will produce the following code

Interval...
(0, 20]

Interval length...
20
