# Overview

A **set** in [Python](https://www.educative.io/answers/what-is-python) is a linear data structure used to store elements without allowing duplicates. But it doesn't allow indexing.

A set that allows numerical indexing of the elements is called `IndexableSet` and is provided by the `sortedcollections` module. 

`IndexableSet` follows zero-based indexing.

## Syntax

```
IndexableSet(iterable)
```

## Parameter

- `iterable`: This is an iterable of elements.

## Return value

The method returns a set whose elements can be accessed via indexes.

## Example 

from sortedcollections import IndexableSet

iterable = '85678756'
s = IndexableSet(iterable)

print("Set - ", s)
print("Elements from index 0 to 2 - ", s[:2])
print("Element at index 3 - ", s[3])

## Explanation

- Line 1: We import `IndexableSet` from the `sortedcollections` package.
- Line 3: We define an iterable.
- Line 4: We create an instance of `IndexableSet()` with the iterable defined in line 3.
- Line 6: We print the set.
- Line 7: We print the elements from index `0` to `2`.
- Line 8: We print the element at index `3`.

What is IndexableSet in Python?

IndexableSet in Python, from sortedcollections, is a set that allows numerical indexing, enhancing traditional set functionality with zero-based indexing.
