Python Tutorial

Getting Started with Python

Introduction To Python:

Python is interpreted, most in-demanded, widely used, high level, general purpose programming language. The most important thing about Python is, it is open source programming language. Open source programming languages are publicly and freely available on internet. Anybody can access the code and can modify and distribute the code publicly. The users or programmers do not required to purchase the licence of the softwares. Due to its open nature anyone can easily access this.

Python is used for web development, used in machine learning, artificial intelligence, used for data analysis and data visualization.

Due to its simplified syntaxes Python is easy to learn,read and write the code. It is just like a simple English language.

Python supports to structural, functional, procedural and object oriented programming paradigm.

History of Python:

Python is designed and developed by Guido Van Rossum in the research institute at Netherlands in 1991. It's first release was published in 20th February 1991. The versions of Python are, Python1, Python2 and Python3. The latest version of Python is 3.9.7

This programming language is named Python by name of one of the famous BBC comedy TV show 'Monty Python's Flying Circus'.

It can run on any platform such as Windows, Linux, UNIX, MacOs etc. Programmer can easily access the code and run on any platform.

Some of the filename extensions are .Py, .pyi, .pyc, .pyd, .pyw etc.

Python's interpreter and libraries are easily available on the official website HTTPS://www.python.org

Python is interpreted:

Python source code is interpreted means the source code is converted into bytecode and then executed by Python virtual machine. It do not require compiler like C and C++ programming languages. Simultaneously it converts and execute code.

Features of Python:

Python is simple and easy to learn, read and write to code because it is just like an English language. It's syntax are very simple and straight to write than other programming languages.

It is interpreted so compiler is not required to convert source code into machine understandable form or machine language.

Most important feature is, Python is open source programming language. It's source code is freely available on internet.

Python is rich source of open source libraries.

It supports to the multi programming language paradigm.

Python supports to GUI programming.

Python is integrated with multiple applications.

It is widely used to write machine learning algorithms.

Most important feature of Python is, it is used for data analysis and visualization purpose.

How to Download Python Interpreter on Windows:

Step 1:

Go to the Python's official website. Follow link,

click below link to download Python on your windows

https://www.python.org/downloads/windows/

Step 2:

Select the latest release version of Python to download. When I published this article the latest version of Python was Python 3.9.7.

Select Python installer as per your operating system. If your operating system is windows 32 bits then select the Python installer for Windows 32 bit, if your operating system is windows 64 bits then select Python installer for Windows 64 bit.

You will find windows installer in this way select appropriate installer.

Click here to download Python for Windows 64 bit OS -. https://www.python.org/ftp/python/3.9.7/python-3.9.7-amd64.exe

Click here to download Python for Windows 32 bit OS-- https://www.python.org/ftp/python/3.9.7/python-3.9.7.exe

Note that 3.9.7 is a latest version at the time of publishing the article and will not work on prior versions of windows 7.

Step 3:

Select the installer (.Exe file of Python) on your machine and double click on it. You will get installer window. Make sure to check the check boxes. And click on install now. When you will get message of successful installation then click on disable path length limit. Now you have done.

Step 4:

Installation is completed now. Check whether it is properly installed or not by running it.

Go to the command prompt. From start windows button check program list you will find command prompt. Another way to find command prompt just type .cmd at the search box you will get command prompt. On the command prompt just type Python or py and press enter key. If Python is properly installed then command prompt will shows details about Python means it's version and other details. If it is not installed it will navigate you to microsoft store to download Python.
