Python Pandas - Construct an IntervalArray from an array-like of tuples and return the left endpoints of each Interval

To construct an IntervalArray from an array-like of tuples, use the pandas.arrays.IntervalArray.from_tuples() method. To return the left endpoints of each Interval in the IntervalArray, use the array.left property.

At first, import the required libraries −

import pandas as pd

Construct a new IntervalArray from an array-like of tuples −

array = pd.arrays.IntervalArray.from_tuples([(10, 25),(15, 70)])

Display the intervals −

print("Our IntervalArray...\n",array)

Get the left endpoints −

print("\nThe left endpoints of each Interval in the IntervalArray as an Index...\n", array.left)

Example

Following is the code −

import pandas as pd

# Construct a new IntervalArray from an array-like of tuples
array = pd.arrays.IntervalArray.from_tuples([(10, 25),(15, 70)])

# Display the IntervalArray
print("Our IntervalArray...\n",array)

# Getting the length of IntervalArray
# Returns an Index with entries denoting the length of each Interval in the IntervalArray
print("\nOur IntervalArray length...\n",array.length)

# midpoint of each Interval in the IntervalArray as an Index
print("\nThe midpoint of each interval in the IntervalArray...\n",array.mid)

# get the left endpoints
print("\nThe left endpoints of each Interval in the IntervalArray as an Index...\n",array.left)

Output

This will produce the following code −

Our IntervalArray...
<IntervalArray>
[(10, 25], (15, 70]]
Length: 2, dtype: interval[int64, right]

Our IntervalArray length...
Int64Index([15, 55], dtype='int64')

The midpoint of each interval in the IntervalArray...
Float64Index([17.5, 42.5], dtype='float64')

The left endpoints of each Interval in the IntervalArray as an Index...
Int64Index([10, 15], dtype='int64')
