How to check if an IntervalArray object is empty

Onyejiaku Theophilus Chidalu

Overview

The is_empty attribute of an IntervalArray object is used to check if the intervals in the object are empty.

An IntervalArray is an object containing interval data such that they are closed on the same side.

Syntax

The is_empty attribute has the following syntax:

IntervalArray.is_empty
Syntax for the is_empty attribute in pandas

Parameter

Since it is an attribute, is_empty takes no parameter value.

Return value

The is_empty attribute returns an array of boolean values (True or False) indicating which of the intervals are empty.

Example

# A code to illustrate the  is_empty attribute of an IntervalArray object.
# importing the pandas library
import pandas as pd

# creating the IntervalArray objects
a = pd.arrays.IntervalArray([pd.Interval(0, 0), pd.Interval(1, 5)])

# printing the IntervalArray
print(a)

# getting the empty and non-empty intervals
print(a.is_empty)
Implementing the "is_empty" attribute of an IntervalArray object

Explanation

  • Line 3: We import the pandas library.
  • Line 6: We create an IntervalArray object a.
  • Line 9: We print the value of a.
  • Line 12: Using the is_empty attribute, we check each interval of a to see if it is empty or not.
