Python is among the most popular coding languages of 2015. People always think that a snake wrote the word Python. Even the Python programming language symbol portrays two snakes, yellow and blue. Still, the story behind the name is a little different. If we speak about Python’s roots, we must not ignore the ABC language of programming because it was the impact of ABCs, which resulted in programming language development and design called Python. Van Rossum served as an event manager of the programming language entitled ABC throughout the early ’80s. While operating on a new decentralized operating system titled AMOEBA, Van Rossum began searching for a programming language with a structure like ABC with access to machine calls from Amoeba. In the late 1980s, Van Rossum started to develop the new script and eventually released the first edition of that language of programming in 1991. The initial release carries a Modula-3 module framework. The programming language was later on named as ‘Python. ‘
Python is an open-source and object-oriented, as well as a high-level and all-purpose language of programming. At the same time, it is used by a good number of designers across the world to create or generate websites, mobile applications, and GUI applications. The distinguishing aspect Python brings to the table is that, by writing fewer and readable code, programmers can flesh out concepts. Additionally, developers may take advantage of many Python bases to minimize the time plus energy needed to create complicated and broad software applications. A variety of high-traffic websites currently use the programming language, namely Google, Yahoo Maps, Yahoo Groups, Shopzilla, the Weekly News, Linux as well as Web Therapy.
People who want to venture into python programming training should approach the right institutions for quality coaching and mentorship. At the moment numerous institutions claim to offer the course but some of them may not have the resources to deliver the program effectively.
Python finds comfort in developing gaming, political, scientific, and educational apps. Developers, however, still use varying programming language versions. As per Python’s market share, data, and usage statistics reported on W3techs, 99.4 percent of websites are using Python 2, while just 0.6 percent of sites are using Python 3. That’s why knowing different versions, together with its development over many years, become essential for each programmer.
How Python has evolved over the past years
Despite being among the common influential coding languages, in December 1989, Guido van Rossum had initially conceived Python as a leisure project. While his office remained locked up during the Christmas season, he was searching for a leisure project during the holidays to keep him busy. He decided to build another scripting language translator and entitled the project as Python. Thus this was how Python was initially planned as a replacement of the language of ABC program. Van Rossum made the program available to the public in February 1991 after creating an interpreter. However, today the Python Software Foundation manages this open-source language of programming.
Python Version 1
Version 1.0 was launched in January year 1994. Its main release aspects included several new elements as well as useful software design tools, which included lambda, map, and filter. The 1.4 was launched with a few unique characteristics such as keyword features, inbuilt back up for compound numbers, as well as an elementary form of hiding data. Two main releases preceded, which is version 1.5 and version 1.6. The first Version did lack some of the attributes that commonly known programming languages of that time had to offer. However, the previous versions provided a solid basis for a powerful and ultramodern program language to evolve.
Python Version 2
Version 2.0 was launched in October 2000, featuring a new list translation function plus a waste collection system. It was stirred by other dynamic software design languages, including Haskell, in the list comprehension feature. Unlike Haskell, however, version 2.0 gave priority to alphanumeric keywords for punctuating characters. Besides, the waste collection framework performed the compilation of reference cycles. Various minor updates supplemented its main release. The updates introduced a variety of functions to the programming languages, such as support for nested choices and the integration of Python programs plus different software to a universal system. Software Framework has declared that there will be no release of version 2.8. This Framework will, however, offer enough funding for the programming language version 2.7 until the end of 2020.
Python Version 3
In December 2008, version 3.0 was launched. It includes several new characteristics and upgrades, together with several discontinued features. The discontinued elements, as well as backward incompatibility, render Python version 3 entirely different from previous releases. So, most Python creators are still using Python 2.6 and 2.7 to benefit from the discontinued elements from previous main releases. Python 3’s new characteristics rendered it more accessible and modern. Many developers have moved to program language version 3.0 to take advantage of these fantastic elements.
Version 3.0 substituted print statement with an in-built print () feature, thus enabling the designers to make good use of custom line filter. Also, it made the laws of comparison simple. If a meaningful or natural order does not order the opcodes, then a Type Error exception may now be created by the comparative ordering operators.
Python version 3 additionally uses data or texts other than 8-bit strings or Unicode. By when treating all code, it represents the encoded Unicode as binary data.
Since version 3 is backward-incompatible, most programmers are unable to use elements such as string exemptions, implicit relative imports as well as old-style classes. The designers also need to be familiar with the syntax and API updates. They can use a “2to3” method for smooth migration of their program from Python 2 to 3. By feedback and alerts, the tool illustrates incompatibility and areas of concern. The feedback help programmers make code improvements and update their current apps to the new programming language version. Python version 2 and version 3 vary entirely from one another
The latest Version
Currently, most programmers choose either version 3.4.3 or 2.7.10. Version 2.7 allows designers to take advantage of the enriched standard library and numeric handling enhancements. This Version simplifies the shifting of designers to Python 3. Version 3.4, on the other hand, arrives with many new features as well as library modules, improvements on security, and enhancements to CPython’s implementation. Nevertheless, in both the Python API and the programming language, a variety of features are deprecated. The developers may also use Python 3.4 in the long run to get support.
Python Version 4
Python 4.0 is supposed to be available by 2023 once version 3.9 is launched. It should come along with elements helping programmers quickly shift from version 3 to version 4. While gaining more experience, the professional designers may also benefit from a range of backward-compatibility components to update their current applications short of investing extra time plus effort into it. Python developers have to wait several years to have a clear picture of version 4.0. They should, however, track the latest launches to move to the standard coding language version 4.0 quickly.
In conclusion, the programmers must, therefore, identify the elements of these different versions, note their contrast on compatibility based on the project’s unique requirements. They also need to check the Python version, which is supported by each system. Nevertheless, every developer should get full advantage of the latest Version to benefit from new aspects as well as long term benefits. The programmers’ community offers assistance to Python users at all times. Python code, as we already know, is freely available to all. Therefore, thousands of programmers around the world are working to find vulnerabilities and build patches to correct those vulnerabilities. Besides, many people make new language modifications and submit them for approval.
