Function & Library for Merge Sort in Python (2 Examples)
In this article, I’ll show how to use the sorting library to implement the merge sort algorithm in the Python programming language.

Example Data & Libraries
Firstly, let’s import the sorting project which will be used to work with a pre-developed merge sort algorithm. sorting project is an open-source project developed by a fellow programmer known by the alias yoginth.
import sorting # importing sorting library
Now let’s create some example lists. One is an integer list called data, the other is a string list called data_str.
data = [1, 8, 3, 5, 6, 9, 2, 4] # creating sample list of integers data_str = ['stat', 'abc', 'hello'] # creating sample list of strings
Without further ado, let’s see how to use the function running the merge sort algorithm.
Example 1: Sort an Integer List via the sorting.merge() Function
The function sorting.merge() can be easily utilized to sort the integer list data, as shown below.
res = sorting.merge(data) # sorting the list of integers print(res) # [1, 2, 3, 4, 5, 6, 8, 9]
The printed result shows that the list data is successfully sorted.
Example 2: Sort a String List via the sorting.merge() Function
In this example, I’ll show how a string list can be sorted using the sorting.merge() function.
res_str = sorting.merge(data_str) # sorting the string list print(res_str) # printing the sorted string list # ['abc', 'hello', 'stat']
As you can see with a single line of code we managed to sort the string list data _str.
