Hire Python 3.x Developers

About Python
In comparison with many languages, Python is easy to grasp and use. It uses more straightforward commands to function and lesser text than most other languages. It’s evident in the popularity of Python among coders, students, and tech companies. It wouldn’t be exaggerating to say that Python, the pervasive programming language,  has found an essential place in our lives. Its integral presence in our lives says it all - mobile devices, online searches, and games, to name a few. 

The year 1991 saw the inception of the Python, which was created by a Dutch programmer named Guido Van Rossum. Since it is an interpreted language, it comes with an interpreter that executes the program directly instead of relying on complicated machine languages. Also, the language is open source, which makes it accessible for anyone who wants to contribute to it. Much like the English language, it’s readable, understandable, and easy to use. It’s one of the preferred languages of top companies - Google, Wikipedia, CERN, and NASA, to name a few.

The first version, Python 1.0, was published in February 1991. Python 2.0 came out on October 16, 2000. Meanwhile, Python 3.0 came out on December 3, 2008. This version of Python is not backward compatible with its predecessor. It put particular emphasis on the removal of repetitive programming constructs. Python 3.8.1 is the latest version of Python 3.

What is Python 3?
In December 2003, Python 3.0 was released to address those issues which existed in Python 2. It’s not backward compatible, and some of its features were backported to Python 2.x versions to ease the migration process in Python 3.0. Consequently, any organization that was using Python 2.x had to incorporate several changes to migrate their project to 3.x. These changes not only pertain to projects and applications but also all the libraries of the Python ecosystem.

Why should you use Python 3?
Below are some noteworthy reasons why developers should use Python  3.x  version:

  • It supports all the modern techniques - AI, Data Science, and Machine Learning to name a few
  • It includes a large community of Python developers where members help each other
  • It is easier to learn compared to previous versions
  • It presents users with powerful libraries and toolkits
  • It is easy to link between components written in other languages easily

Most developers grapple with the question of which Python version to use. However, Python 3 is the downright winner because the olden versions may be discontinued in times to come. And Python 3 is the only version that’ll receive updates for security and bug fixes. The sooner developers will realize that older versions of Python will no longer be supported, the sooner they’ll switch to Python 3.x. However, if a job requires programming on Python 2, that would make only sense to use this version.

Q Why is Python 3 better than Python 2?
A. Given below are some points of difference which you can use to determine the better of the two Python versions:

  • The syntax of Python 3 is simpler and more understandable than Python 2
  • Unicode is the default storing of strings for Python 3 whereas Python 2 stores requirement include defining Unicode string value with  “u’’  
  • Python 3 provides parenthesis for enclosing the exceptions whereas Python 2 includes notations
  • The value of variables in Python 3 never changes whereas the value of the global variable changes in Python 2 (while using the statement inside the for loop)
  • The rules of ordering comparisons in Python 3 are more straightforward than the rules in Python 2
  • In Python 3, the range () is used to perform iterations whereas, Python 2 uses the range() for iterations
