The programming language that has brought the realm of technology to an entirely different level is Python. This general-purpose programming language discovered its application in various fields, including Data Science, Natural Language Processing, Artificial Intelligence Software Engineering, etc. The two most popular Python versions of Python that were released in the public domain were Python 2 and Python 3. Even though they're two different variations of the same language, you will notice some striking differences between the two versions, and it's a lot of fun to examine the distinctions between Python 2 and Python 3. There were many debates over the issue of which of the two versions is superior to utilize.
Python 2.0 was released to the world of technology in 2000. The program was created in 2000 by BeOpen Python Labs, the BeOpen Python Labs team; its introduction to Python 2 was to make programming straightforward to master for the general majority of people.

Python 2 successfully implemented the technical specifications in the Python Enhancement Proposal (PEP). After the introduction to Python 3, Python 2 was unable to find much usage in technology. In 2020, it was the year that ended the Python 2 legacy, and Python 2.7 was the most recent version. Below is a list of dates of the launch of various variations of Python 2. X series:
Python 3 took place in 2008; Python 3 was not simply a new release from Python 2 after debugging. The launch to Python was mostly accompanied by the idea that redundancy - creating repetitive codes or the same line of code repeatedly must be removed from programming. Python 3 is backward incompatible and seeks to solve novice programmers' difficulties when learning the programming language. Below is a timeline of the launch of the different variations of Python 3. X series:

There were many reasons why there were various variants that used Python available. First of all, the majority of code for the industry had been previously written using Python 2; moving from Python 2 to Python 3 could be a laborious and costly task.
Additionally, to work with configuration management tools such as puppet or ansible, you must know the two versions of Python 2 and Python 3 were necessary. But it was discovered that Python 3 had been created to work with many different areas like web development, data science, analytics scripting, among others. Python 3 has a lot of libraries with rich features and is easily integrated into other programming languages. Thus, the necessity for the two different versions of Python is easy to comprehend. Attempts were put into making Python 3 support a lot of the significant functions that Python 2 offered, and in the year 2020, Python 2 saw its death.
With an in-depth knowledge of the background of both main versions of Python and Python 3, let's examine the primary difference between the two versions; let's dive in and discover which one the winner is in the contest: Python 2 Vs. Python 3.
Global variables alter with Python 2 if utilized in a loop.
The value of variables is never changed with Python 3.
With Python 2, the range() function is specified to perform iterations.
The Python 3 version introduced Python 3, the new Range() function was added to allow iterations.
Many libraries from Python 2 are not forward compatible with Python 2
Many libraries were developed using Python 3 to be strictly utilized in conjunction with Python 3
A ubiquitous question that must be on every person's thoughts after reading this article to the point of this article can be Which Python Version is Better? Python 2 or Python 3? If you've been paying attention to the topic up to now, the answer appears pretty straightforward. It's Python 3 that is the winning version.

First off, Python 2 is no longer in use after 2020. Python 3 felt like the best choice, especially for students who were unsure if they wanted to pursue it. Python 3 is easier to comprehend, readable, and is more well-known than Python 2. Python 2 has run out of steam. One must learn Python 2 if a legacy program was developed with Python 2 or if a business requires the developer to transfer to Python 3. Python 2 code into Python 3.
The image below illustrates the apparent trends in a sense. Python 2 has lost its appeal. Python 2 has lost the programmers' attention with time, and how Python 3 has won the contest between Python 2 and Python 3. So, it is safe to claim that, as of 2021, the issue of "Which Python Version is Best?" has a clear winner: Python 3.
In the end, we'd like to state that Python is among the most sought-after languages of our times, as it is used extensively in numerous areas. The promising fields of the future, such as Artificial Intelligence(AI), Data Science, are primarily based heavily on Python and its library, as well as frameworks such as Numpy, Pandas, etc.
So, if any young programmer is looking to begin their programming profession, Python might be an excellent option. Through this article, we hope to highlight the differences between two main versions of Python, which are Python 2 as well as Python 3 and determine the reasons Python 3 will be the preferred version that will be used in the future.
Hope this article is helpful to you, thanks for reading.
