Python Pandas - Get the left bound for the IntervalIndex

To get the left bound for the IntervalIndex, use the interval.left property in Pandas. At first, import the required libraries −

import pandas as pd

Create IntervalIndex −

interval = pd.IntervalIndex.from_arrays([5, 10, 15], [15, 20, 25])

Display the interval −

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

Get the left bound −

print("\nThe left bound for the IntervalIndex...\n",interval.left)

Example

Following is the code −

import pandas as pd

# Create IntervalIndex
interval = pd.IntervalIndex.from_arrays([5, 10, 15], [15, 20, 25])

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

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

# Check whether the IntervalIndex is closed on the left-side, right-side, both or neither
print("\nChecking for the type of IntervalIndex...\n",interval.closed)

# Get the left bound
print("\nThe left bound for the IntervalIndex...\n",interval.left)

Output

This will produce the following output −

IntervalIndex...
IntervalIndex([(5, 15], (10, 20], (15, 25]], dtype='interval[int64, right]')

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

Checking for the type of IntervalIndex...
right

The left bound for the IntervalIndex...
Int64Index([5, 10, 15], dtype='int64')
