In this lesson, you will learn how to code sorting algorithms in Python. You will learn two of the most popular sorting algorithms, the selection sort and the merge sort which is also known as a divide and conquer sort algorithm.
Timsort uses the newly introduced left and right parameters in insertion_sort() to sort the list in place without having to create new arrays like merge sort and Quicksort do. Line 16 merges these smaller runs, with each run being of size 32 initially. With each iteration, the size of ...

In the first example, we will try to sort a number tuple. Here, we will see that, with this sorted function, the tuple will be converted to a list and then sorted. numbers = (10, 33, 7, 80, 55, 2) numbers=sorted(numbers) ...
