Get Length from IntervalIndex in Python Pandas

To get the length from the IntervalIndex, use the interval.length property in Pandas. At first, import the required libraries −

import pandas as pd

Create IntervalIndex −

interval = pd.IntervalIndex.from_arrays([10, 15, 20], [20, 25, 30])

Display the interval −

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

Display the interval length −

print("\nIntervalIndex length...\n",interval.length)

Example

Following is the code −

import pandas as pd

# Create IntervalIndex
interval = pd.IntervalIndex.from_arrays([10, 15, 20], [20, 25, 30])

# Display the interval
print("IntervalIndex...\n",interval)

# Display the interval length
print("\nIntervalIndex length...\n",interval.length)

# return the midpoint of the Interval
print("\nThe midpoint for the Interval...\n",interval.mid)

Output

This will produce the following output −

IntervalIndex...
IntervalIndex([(10, 20], (15, 25], (20, 30]], dtype='interval[int64, right]')

IntervalIndex length...
Int64Index([10, 10, 10], dtype='int64')

The midpoint for the Interval...
Float64Index([15.0, 20.0, 25.0], dtype='float64')
