Python 3 Installation & Setup Guide – How to use Python 3 in Windows

What are the programming languages

A programming language is a set of grammatical rules for instructing a computer device to perform a specific task. There are two types of programming languages Low-level Programming languages or high-level programming languages.

In the beginning, the programmers were programming in low-level programming languages like Machine language (Binary)i.e.  First-generation-programming-language (1GL)  and Assembly i.e. Second-generation-programming-language (2GL) but these languages were making programming process slower or harder.
In the 1950s the first high-level programming language or Third-generation language(3GL) i.e.  Plankalkul were written by Konrad Zuse.


Why we need Programming languages 

A computer is an electronic machine that follows IPO (Input-Process -Output) Cycle process so that if you want to do work by the computer then you will need a Programming Language.
Just like if we want to execute the sum of two or three (2+3=) from the computer then we have to use a programming language to give instructions to the computer then the computer will provide us output as 2+3=5.

Why Choose Python Programming Language

As you know that Python is English keyword syntax-based programming language which makes programming so easier for both technical person or non-technical person means if you don`t have any knowledge about programming then you too can be a good programmer with the help of Python. Most of the programmers also prefer Python because other languages like C language, C++, JAVA, PHP or many more are using syntaxes based on the punctuation but Python using English Keyword as syntex so that anybody can learn it easily.

How do I download and install Python on the window?

Python is available in two versions first Python 2 or second Python 3. Python 2 is an old version that will no longer exist it will reach its end till 2020 but Python 3 is the latest versional. Recently Python 3 released a new version 3.7.3  on 25 march 2019 so you should install it follow the below-given instructions:-

• Open a browser (Chrome, Firefox, Opera, etc.) and navigate Python.org 
• At the top heading says Python Release for the window and click on the link for the latest version i.e. Python 3.7.3

• Then Scroll down and select either 64-bit or 32-bit

Note:- If your system has a 64-bit processor then you should choose a 64-bite installer. 
If your system has a 32-bit processor then you should choose a 32-bite installer.
If you don’t know which one version your system has then you can choose 64-bit

• After downloaded file then simply double click on the downloaded file and run it.
• Then a window will open and you will see two checkboxes (at the left side in the bottom) make sure to fill out both boxes then click on the install now option and installation will start.

• Then you will see a window of successful installation now Python is installed on your system so you can close that window.

• Now you can start using Python in your system

Note:- If you did any mistake during installation and Python is not working properly then don’t worry simply uninstall it and then re-install Python again carefully from Python.org.

How to use Python after installation

• If you installed Python successfully then navigate Python Compiler i.e. IDLE. You can navigate it through window search bar type IDLE in the search bar and click to open compiler.
• After the opening of compiler now you need a new file so press Ctrl+N for the new file in this file you can make any program
• After creating a program in the new file then save it and press F5 to run the program. Python file should be saved by using Python extension like .py,.pyc,.pyd,.Pyo, .pyw,.pyz but i recommend .py mostly programmers use this extension.

IDLE is the best IDE for Python learning it is a
 lightweight and easy to use so if you are a learner then I recommend you IDLE.

If you don’t want to use Python IDLE then you can use other Code editing tools PyCharm, Wing IDE, PyDev, Spyder, Atom, Thonny, PyScripter, etc. These toll provide feature such as build automation, testing, code linting or debugging so by the tools you can speed up of your work

Create the First program in Python 

Programming in Python is very simple just like if you want to create ‘HELLO WORLD’ in Python then you have to write only Print(“HELLO WORLD”). Now you can run it Then you will see HELLO WORLD has printed on the screen so now you can imagine the programming in Python how is simple compared to others like C++ or JAVA.
