What is Python 3? Know Python 2 VS Python 3

Prior to its introduction in the year 1991, Dutch programmer Guido van Rossum was working on Python from the late 1980s. He developed Python utilizing an unsuccessful program known as the ABA language created by Centrum Wiskunde & Informatica research institute.

Rossum changed the program into a simple, modern language that would transform the programming world. It was designed as an underlying scripting language for Amoeba, a distributed operating system utilized for the CWI.

As Python developed with the release of significant releases and improved its accessibility and ease through the editing by another programmer, it has evolved into an exceptionally frequently utilized and studied language. It has been a significant influence on the creation of Perl and Ruby and other more complicated languages.

Python 3
Today, many companies using Python have grown to incorporate famous names such as Netflix, Uber, Spotify, Reddit, Instagram, and many more.

Today, many companies using Python have grown to incorporate famous names such as Netflix, Uber, Spotify, Reddit, Instagram, and many more. Many are working on changing their backend code to make it compatible with Python.

Let’s understand the concept in deep.

Why are companies moving away from Python 2 to Python 3?

For the purpose of learning, a lot of beginner users are upset about which version to choose? There is also conflict between Python 2 and 3 within the community. Some believe the argument that version 2 is more advantageous than Python 3. In this article, we’re going to look at the main distinctions between version 3 and 2 and the best one to pick for your career in programming and software development too.

What exactly is Python 3?

Python 3 is considered as an option of Python. It is a new version that Python is currently in development. It is a significant component that is part of new version, released in 2008 to fix the bugs and problems that existed in Python 2.

The primary goal in Python 3 development is to tidy up the codebase and eliminate redundancy which makes it evident that there was only one way to accomplish the task.

What exactly is Python 2?

Python 2 was officially released on February 20, 1991; Guido Van Rossum developed that. It was one of the frequently utilize programming languages on the market. Python developers added a great syntactic sugar that made Python the language easier to master when they were developing. They created a great library stack that made developers’ lives easier. Python 2 supports procedural, functional, and Object-Oriented Structural Programming Paradigms. Additionally, it has an automatic garbage collector to help with better management of memory.

Which are the main reasons for Changing to the New Version?

Today, companies still employ Python 2 for legacy reasons. However, most enterprises are now using Python 3 because of the new features that have been implemented. These are:

FeaturesPython 2Python 3
Integer DivisionWith Python 2, the general division operation produces an integer result.For Python 3, the general division operation produces the result as floating points.
Character EncodingWhen using Python 2, the character is encoded using ASCII format, which is stored. Strings are stored as ASCII values by default. You must add “u” to save strings in Unicode format.When using Python 3, the character encoder is Unicode and is based on Unicode. The strings are saved in UTF-8 format. It can store a massive number of characters. Unicode encoders can encode different languages’ characters and Emojis in addition.
Improving Library StandardsA lot of libraries built on Python 2 are not compatible with Python 3. Therefore, the implementation of libraries to Python 3 is changed completely. The developers are rebuilding Python 2 libraries to ensure compatibility. Python 2 libraries for suitable compatibility with Python 3 version.Python 3 has good standards and a robust library above Python 2 . Many Machine Learning and Deep Learning libraries are updated and improved to facilitate model development.
Input FunctionWithin Python 2, to take the user’s input, two kinds of functions are to be used.raw input(): The raw_input function will change the input type to a string.input(): This function uses the value and kind of input you type in as-is without changing any type.In Python3, only the default function can take data from users, i.e., input(). This function works like input(), which is a raw_input(). It converts the input into a string type.

Conclusion:

As per the facts, Python 2 cannot be utilize for Software development. To avoid this issue, companies are shifting towards Python 3, which has many features, is compatible with other platforms, and is superior to version 2. Therefore, it’s recommended to use Python 3 for your programming career and software development.
