Introduction to Timsort
Python’s built-in sorting algorithm, Timsort, is a hybrid sorting algorithm derived from merge sort and insertion sort. It is designed to perform well on many kinds of real-world data. Timsort has been Python’s standard sorting algorithm since version 2.3.
Usage of Timsort
Timsort is not only used in Python, but also to sort arrays of non-primitive type in Java SE 7, on the Android platform, and in GNU Octave. This wide usage of Timsort in different platforms and languages shows its efficiency and versatility.
How Timsort Works
Timsort begins by scanning the list to be sorted to find ‚runs‘ of increasing or decreasing elements. These runs are then merged together to create larger sorted lists, until only one sorted list remains.

return sorted(arr)Advantages of Timsort
One of the main advantages of Timsort is its efficiency. It has a worst-case and average time complexity of O(n log n), making it one of the most efficient sorting algorithms available. Furthermore, Timsort is a stable sort, meaning that equal elements maintain their relative order after sorting.
Conclusion
In conclusion, Python’s Timsort is a powerful and efficient sorting algorithm that is widely used in various platforms and languages. Its efficiency and stability make it an excellent choice for sorting real-world data.
