What’s New In Python 3 Guide Installation and Setup

As you might be knowing that Python is a high-level, interpreted scripting language. It was developed in the 1980s by Guido van Rossum at NRIMCS in the Netherlands.

The most popular version of Python was 2.0 lately. It was released in 2000 and consecutively updated as a 2.x version every year till today. But now the update process has been very slow as most of the people are now migrated to Python 3.0.

Python 2.0 and Python 3.0 are very much similar to each other with little but significant changes among them. Also, Python 3.0 was not backward compatible with Python 2.x versions. That is why code developed in 2.x was not easily transferable to the latest version of the Python 3.x versions.

But finally, Python 2.x updates were ended with the release of the last version known as Python 2.7.15. So, now Python 2.x version is not maintained and no security updates are provided to its codebase.

Reasons to Learn Python

If you are new to programming and still confused, searching which language to learn and start your career with. Let me tell you the real reasons to learn Python 3 in the current scenario.

Python is Popular

Yes, Python is the most popular language on the planet. As you can see in the below Graph from PYPL. Python is on the top of the list.

Python is growing over the last few years. Most of the popular universities started teaching their basic programming courses in Python. According to research on Dice Python is one of the hottest skills to have and the most popular programming language in the world.

Python is Free, Simple, Portable and Interpreted Language

Most of the languages you know such as C++, JAVA, etc are compiled, meaning once you have written the code you need to convert it to machine code to run it for which compiler is used. Whereas Python is Interpreted language means you are not required to convert the code in Machine Language. You can run Python code directly without any compilation.

This makes Python development a lot quicker. Also, it removes too many block holes. But interpreted languages also come with downsides which are slowness. Yes, Python cannot be run at the speed a C++ code will run on the system. Hence there is a trade-off for things.

The Python interpreter is developed under an OSI-approved open-source license, making it free to install, use and distribute, even for commercial purposes. Python interpreter is available for all the platforms available currently, for example, Windows, Unix, macOS, smartphones and tablets, and probably anything else you ever heard of.

Since Python code is interpreted and is not compiled for machine instructions it’s quite portable. One code written for one platform will work on all other platforms as well if Python is installed there.

And Finally, Python is the most simple language to learn on the planet. Its syntax and readability are very simple and easy to understand. Python code has a simple and clean structure that is easy to learn and easy to read. As you will see, the language definition enforces a code structure that is easy to read.

Installation and Setup of Python 3

Python 3 installation is very simple and easy to achieve. All you are required to do is based upon your operating system download the required installation file and then start the installation.

Alternatively, several websites allow you to access a Python interpreter online without installing anything on your computer at all.

For Windows:

Step 1: Download the Python 3 Installer

Important: You want to be sure to check the box that says Add Python 3.x to PATH as shown to ensure that the interpreter will be placed in your execution path.

You can follow the same instructions on the Python.org page for the installation of python on other platforms apart from windows. It’s not much of the difference. But in case you find any difficulty let us know in the comment section in which case we can help you immediately with installations.

Conclusion

You should start learning Python from today if you are new to programming, or you are about to start or you are already a programmer. Python gives you lots of toolsets and skills to be added to your resume. Most industries are looking for skilled Python developers nowadays.

And a Python on your resume will surely give you an edge over others who do not know Python. Python lets you expand further in the world of Web Development, Data Science, and many more things. So, in this current world scenario Python is must learn the language.
