Introduction to Versions of Python
Python is a widely used website or web-based application development technique known for its object-oriented characteristics such as increased efficiency, superior performance, dependability, and so on. Python has been published in many versions since 1994, including Python 1.0, Python 1.5, Python 1.5.2, Python 1.6, Python 2.0, Python 2.0.1, and so on. Python 2.7.13 was published on December 17, 2016, Python 3.5.3 was released on January 17, 2017, Python 3.6.10 was released on December 18, 2019, and Python 3.8.2 was released on February 24, 2020.
Python is created by Guido Russom. Python has almost unlimited powers. When we look at the Python code, it is pretty simple to grasp. It does not always employ curly brackets to indicate the specific scope. Instead, it use whitespace. In general, four spaces are used to specify the specific scope in Python, according to convention. We are commonly referring to two Python versions, 2.x and 3.x. Python 2.x will be obsolete by 2020. Any further assistance is not offered. As a result, it is best to begin with the 3.x version. As I write this, the current version of Python is 3.7.3. 3.8 is also in the works.
Python 2 vs Python 3
As a novice, everyone questions if they should study Python 2 or Python 3. Python 3 is the solution. Since they are basically the same, Python 3 only has a few new features. If you are familiar with Python 2 and wish to learn Python 3, you can do it quickly.
The distinction is similar to Python 2; you print something like
below:
print “Hello World!”
Nevertheless, in Python 3, we append parentheses to the print statement as follows:
below:
print(“Hello World!”)
There is no hard and fast rule for choosing one of them, but in my view, you should go with Python.

How to Install Python?
If you are using a MAC or Linux, Python is already installed on your system. But what if you’re standing outside the window? Python must be installed on the Windows operating system.

Then go to Downloads. Then install the most recent version according to your needs.
requirement.
Python 3
Python 3 is a better version. Unicode characters are supported. When we dive some number, we get the precise result. Before in Python 2, we obtained a rounded value for the same. The majority of IT organisations are migrating to Python 3. With each updated version, it becomes quicker. Python also has a large library support for python3. Python 3 is the language used by companies such as Facebook and Instagram. The most essential thing to remember is that Python 2.7 will no longer be supported after 2020. Is Python2 still required then?
- Yes, you can’t say it’s fully vanished. Some companies are still stuck to python 2.7. There are using some libraries which are not fully supported by python 3. If you follow to code using Python 3, you need to learn python 2.7. Even if you are using 2.7 versions, don’t worry. Because all the code we write in python older version can be easily upgraded to the newer version of python.
- Now we have seen a lot of things related to the python version. Now you have decided to learn python. But the next question is where to start. How to plan your python learning? Don’t worry today; I am going to share with you some of the learning material. First thing, there are a lot of things available online for free. for python first, you need to check whether it is on your machine or not.
You may test this by running the following command.
- Go to your command prompt or terminal if you are on MAC.
- Write “Python” and simply enter
- You will get the message with version no of python and some information.
- Suppose it does not exist on your machine. Then you will get a message like ‘python’ is not recognized as an internal or external command, operable program or batch file.
- If you don’t have one, install it with some simple installation steps mentioned above from python’s official site.
Versions Python2 and Python3 can be used on the same machine?
Absolutely, if you have a need for both, you may run both versions on the same PC. But, each time you work on a certain project at that moment, you must remember the version you are working on. It would be preferable if you could prevent conflicts between the two versions.
If Python 2.7 is installed by default, you must install Python 3.
explicitly.
Future Scope of Python
- We can say that Python is having an endless scope because today, in every area, python is working as a helping center. Python is everywhere in Big data, web designing, automation, AI, machine learning, etc., and these technologies are the future of IT.
- Python has a lot of community support. And many programmers grow with this support very quickly. If you stuck somewhere, you could find the way by these communities out there. Python is designed in a way that makes some lines of code in a single line. Programmers love to write this way.
Consider the two cases below. Python Source Code:
Print (“Hello World!!!”) Java Source Code:
class Abc{
public static void main(String[] args){
out.println(“Hello World!!!”);
}
}
As you can see, Python makes it easier to create code. Python is an interpreted language, therefore it runs faster. Python is one of the most popular programming languages among programmers. Python’s most popular feature is its ease of integration with other languages. Jython allows Python to communicate with Java. This language may be learned on its official website.
