Visualize an Interesting Sorting Algorithms With Python

There are various types of sorting algorithms out there and sometimes it becomes very difficult to understand their internal working without visualization. Hence I decided to visualize these sorting algorithms in python with the help of matplotlib.animations library.

NOTE:- In this article, we will also compute the number of operations performed and will be able to see the time complexity of the sorting algorithm.

As our purpose is to only visualize the sorting algorithms hence I will be using the merge sort for a demonstration but you should implement the rest of them in order to understand the differences among them.

Before we start coding, you must have python 3.3 or above installed because I have used the yield from feature or generator.

Let’s Start:-

Firstly you need to import the given libraries. We have used the random module in order to generate a random array of numbers to be sorted. The matplotlib pyplot and animation modules will be used to animate the sorting algorithm.

import random
import matplotlib.pyplot as plt
import matplotlib.animation as anim

Below the given swap function will be used to swap the elements in the given array. Defining a separate function is useful as it will be used exhaustively throughout different algorithms.

def swap(A, i, j):
    a = A[j]
    A[j] = A[i]
    A[i] = a
    ## also in python A[i],A[j]=A[j],A[i]

We have used Merge Sort to demonstrate this visualization because this is the most popular and one of the best sorting algorithms out there. Merge sort follows Divide and Conquer technique for sorting. It divides the array into two subarrays and each of these is sorted by calling the merge sort recursively on them. Our main focus is to visualize the algorithm hence I will not explain the working of it. The following code shows the merge sort. In order to get the intuition on how it works, one can follow this video on youtube jenny’s lecture.

def merge_sort(arr,lb,ub):
    if(ub<=lb):
        return
    elif(lb<ub):
        mid =(lb+ub)//2
        yield from merge_sort(arr,lb,mid)
        yield from merge_sort(arr,mid+1,ub)
        yield from merge(arr,lb,mid,ub)
        yield arr
def merge(arr,lb,mid,ub):
    new = []
    i = lb
    j = mid+1
    while(i<=mid and j<=ub):
        if(arr[i]<arr[j]):
            new.append(arr[i])
            i+=1
        else:
            new.append(arr[j])
            j+=1
    if(i>mid):
        while(j<=ub):
            new.append(arr[j])
            j+=1
    else:
        while(i<=mid):
            new.append(arr[i])
            i+=1
    for i,val in enumerate(new):
        arr[lb+i] = val
        yield arr

Why use Python for Software Development

No programming language is pretty much as diverse as Python. It enables building cutting edge applications effortlessly. Developers are as yet investigating the full capability of end-to-end Python development services in various areas. 

By areas, we mean FinTech, HealthTech, InsureTech, Cybersecurity, and that's just the beginning. These are New Economy areas, and Python has the ability to serve every one of them. The vast majority of them require massive computational abilities. Python's code is dynamic and powerful - equipped for taking care of the heavy traffic and substantial algorithmic capacities. 

Programming advancement is multidimensional today. Endeavor programming requires an intelligent application with AI and ML capacities. Shopper based applications require information examination to convey a superior client experience. Netflix, Trello, and Amazon are genuine instances of such applications. Python assists with building them effortlessly. 

5 Reasons to Utilize Python for Programming Web Apps 

Python can do such numerous things that developers can't discover enough reasons to admire it. Python application development isn't restricted to web and enterprise applications. It is exceptionally adaptable and superb for a wide range of uses.

Robust frameworks 

Python is known for its tools and frameworks. There's a structure for everything. Django is helpful for building web applications, venture applications, logical applications, and mathematical processing. Flask is another web improvement framework with no conditions. 

Web2Py, CherryPy, and Falcon offer incredible capabilities to customize Python development services. A large portion of them are open-source frameworks that allow quick turn of events. 

Simple to read and compose 

Python has an improved sentence structure - one that is like the English language. New engineers for Python can undoubtedly understand where they stand in the development process. The simplicity of composing allows quick application building. 

The motivation behind building Python, as said by its maker Guido Van Rossum, was to empower even beginner engineers to comprehend the programming language. The simple coding likewise permits developers to roll out speedy improvements without getting confused by pointless subtleties. 

Utilized by the best 

Alright - Python isn't simply one more programming language. It should have something, which is the reason the business giants use it. Furthermore, that too for different purposes. Developers at Google use Python to assemble framework organization systems, parallel information pusher, code audit, testing and QA, and substantially more. Netflix utilizes Python web development services for its recommendation algorithm and media player. 

Massive community support 

Python has a steadily developing community that offers enormous help. From amateurs to specialists, there's everybody. There are a lot of instructional exercises, documentation, and guides accessible for Python web development solutions. 

Today, numerous universities start with Python, adding to the quantity of individuals in the community. Frequently, Python designers team up on various tasks and help each other with algorithmic, utilitarian, and application critical thinking. 

Progressive applications 

Python is the greatest supporter of data science, Machine Learning, and Artificial Intelligence at any enterprise software development company. Its utilization cases in cutting edge applications are the most compelling motivation for its prosperity. Python is the second most well known tool after R for data analytics.

The simplicity of getting sorted out, overseeing, and visualizing information through unique libraries makes it ideal for data based applications. TensorFlow for neural networks and OpenCV for computer vision are two of Python's most well known use cases for Machine learning applications.

Summary

Thinking about the advances in programming and innovation, Python is a YES for an assorted scope of utilizations. Game development, web application development services, GUI advancement, ML and AI improvement, Enterprise and customer applications - every one of them uses Python to its full potential. 

The disadvantages of Python web improvement arrangements are regularly disregarded by developers and organizations because of the advantages it gives. They focus on quality over speed and performance over blunders. That is the reason it's a good idea to utilize Python for building the applications of the future.
