If x = len(left): # if at the end of 1st half, # The value from the left half has been usedīottom-up approach implementation of merge sort in python as below.įor k in range(0, len(left) + len(right)): key has the value of a function that will be called on each item in the list. # Two iterators for traversing the left and right half The sort () method can take in two optional arguments called key and reverse. The recursive approach of implementing the merge sort Given below are the examples mentioned: Example #1 The sorted () function has no effect on the original iterable sequence as it provides a new sorted output. Finally, we will merge all sub-lists with solutions to get the final list that will be in sorted order. Use the sorted () Function to Sort a Set in Python The sorted () function is a built-in function in Python that returns a sorted sequence (list,tuple,string) or sorted collection (sets,dictionary) in the form of a list.We will divide the sub-lists into further sub-lists as atomic problems by following the process in step 2. Python’s Built-In Sorting Algorithm The Python language, like many other high-level programming languages, offers the ability to sort data out of the box using sorted ().Using start and end variables, we will find the middle of the list by using the formula as (start+end)/2 and store the result in variable mid, and we will divide the list into 2 sub-lists as a start to mid as one sub-list and mid+1 to end as another sub-list.0 in it, and the end will store the length of the list, i.e. We will take two variables, “start” and “end”, where “start” will store the starting index, i.e.In the merge sort implementation, we follow the below steps:
