# Timsort algorithm

Timsort is used as the default standard sorting algorithm in all Python versions >=2.3. The Timsort algorithm is an optimal algorithm for real-world long lists that is based on a combination of the merge sort and insertion sort algorithms. The Timsort algorithm utilizes the best of both algorithms; insertion sort works best when the array is sorted partially and its size is small, and the merge method of the merge sort algorithm works fast when we have to combine small, sorted lists.

The main concept of the Timsort algorithm is that it uses the insertion sort algorithm to sort small blocks (also known as chunks) of data elements, and then it uses the merge sort algorithm to merge all the sorted chunks. The main characteristic of the Timsort algorithm is that it takes advantage of already-sorted data elements known as “natural runs,” which occur very frequently in real-world data.

The Timsort algorithm works as follows:
